Top 8 Data Science Use Cases in Marketing

In this article, we want to highlight some key data science use cases in marketing.

As far as the key aim of data science is to turn data into actionable insights the marketing sphere cannot skip the application of these insights for its benefit. Big data in marketing provides an opportunity to understand the target audiences much better.  

Data science is mostly applied in marketing areas of profiling, search engine optimization, customer engagement, responsiveness, real-time marketing campaigns. Moreover, new ways to apply data science and analytics in marketing emerge every day. Among these, the new use cases include digital advertising, micro-targeting, micro-segmentation, and many others.  

Let us concentrate on several instances that present particular interest and managed to prove their efficiency in the course of time.   

Customer segmentation

All customers are individuals. Therefore, a one-size-fits-all approach is not efficient at all.  Customer segmentation comes to the rescue of the marketers in this case. Application of the statistical analysis allows marketers to slice the data and group customers.

Customer segmentation is a process of grouping customers into segments according to the coincidences of particular criteria in their characteristics.

There are three significant segmentation types that are the most often used. These are:

segmentation based on touchpoint engagement

segmentation based on purchase patterns.

Application of micro-segmentation appears to be a rising trend in marketing. Micro-segmentation is far more advanced. It helps to segment people into more precise categories especially concerning behavioral intentions. Thus, marketing actions may be tailored to the preferences even of the least numerous customer groups.

Customer segmentation

Real-time analytics

Real-time analytics proved to bring marketing insights into campaigns immediately. These real-time marketing opportunities become possible due to the recent boost in popularity of social media and communication technologies. 

Efficient real-time analysis of data brings a considerable increase in revenues for the companies. Real-time algorithms work with two groups of data: customer data and operational data. 

Customer data provides insights into customers’ wants, preferences, and needs. Operational data reflect various transactions, actions, and decisions made by the customers. Application of real-time data analysis brings efficiency, speed and high-performance rates to marketing campaigns. 

Real-time analytics in marketing provides an opportunity to:

get more details about customers

find the efficient platforms

provide a unique customer experience

run real-time test

identify the best working practices

react and respond immediately.

Predictive analytics

At present, the data is easily accessible and available even for middle-size companies. This is why predictive analytics is so widely applied in marketing. 

Predictive analytics is the application of statistical and machine learning algorithms to predict future with high probability. There are a lot of opportunities to apply predictive analytics in marketing. Let's consider those, which proved to be the most efficient.

Predictive analytics for customers' behavior

Cluster models, predictions, collaborative filtering, regression analysis are all applied to spot the correlation patterns in the customers' behavior to predict future tendencies in purchasing.

Predictive analytics to qualify and prioritize leads

Here belong predictive scoring, identification models and automated segmentation. These are related to qualifying and prioritizing leads to make your marketing efforts more effective. Applying these models, you can make sure that the most effective ready to purchase leads will get your call to action correctly.

Predictive analytics to bring the right product to the market

In this case, data visualization helps the marketing team to make the right decision about what product or service should be delivered to the market.

Predictive analytics for targeting

This is related to a whole bunch of predictive analytics models like affinity analysis, response modeling, churn analysis. These models are used to identify the highest value customers and address them with the right offer at the right time.

Recommendation engines.

Recommendation engines are powerful tools in attempts to provide a personalized experience and high satisfaction rates to the customers. Marketers are those people who should pay particular attention to the application of the recommendation engines.

The key idea of the recommendation engines is to match the preferences of a customer with product features he or she might like. For this purpose, recommendation engines usually use the following models and algorithms: regression, decision tree, K-nearest neighbor, support vector machines, neural networks, etc.

Recommendation engines are a key targeted marketing tool for email and online marketing campaigns.  

Market basket analysis

Market basket analysis refers to the unsupervised learning data mining techniques intended to learn the buying patterns and to disclose the co-occurrence relationships between purchases. Application of these techniques allows predicting future purchase decisions.

Moreover, market basket analysis can significantly improve the efficiency of the marketing message. Besides the type of the marketing message, whether it is direct offer, email, social media, phone call or newsletter you can offer the next best product suitable for a particular customer.

Market basket analysis

Optimization of marketing campaigns 

The main task of the marketing team is to create an efficient, customer oriented, targeted marketing campaign dedicated to delivering the right message to the right people at the right time.  

Optimization of marketing campaign involves the application of smart algorithms and models allowing to increase the efficiency. Modern technologies bring automation to the data collection and analysis process, reduce time spent on them, provide real-time results and spot the slightest changes in patterns. Smart data algorithms treat each customer individually. Thus, the high personalization level becomes more achievable.

The optimization process includes several steps that are equally important and require attention. Let us outline these steps:

Choose the right tools

Invest money in those tools that will efficiently gather and analyze data. Make sure the tools you choose can work together for the benefit of your campaign. Integrate the tools with existing systems and data.

Measure the metrics

Measuring metrics allows to identify processes and strategies that need improvement. Measure the parameters comparing them to your marketing goals.

Draw conclusions

Make right data-based decisions to make your marketing campaign as successful as possible.

Lead scoring

Customers' path through the sales funnel is staffed with various opportunities, options, and choices. Lead scoring is applied to identify those prospective customers who will go through the funnel and make their choice to the benefit of your product or service. What is the trick?

Lead scoring ranks the prospect according to a scale representing the value of each lead. The value of each lead may be identified differently, but often they are referred to as hot, warm or cold ones. 

Lead scoring involves data collection concerning customers' demographics, responsiveness, purchase history, preferences, web page view, visits, likes, shares and even the type of e-mails they often react to. 

As a result of lead scoring, the salespeople get qualified prospects regarding who is highly intended to buy. Thus, when products are offered to the right people, the sales boost. 

Optimal campaign channels and content

The essence of all the marketing efforts is to reach the right customer. However, the marketing landscape has been changed and moved to the online world. Thus, the main task for the companies is to assure a strong online presence for the brand.

The leading part here is given to the selection of optimal digital marketing channels: email marketing, pay-per-click advertisement, search engine optimization, display advertising, Social Media Marketing, content marketing, affiliate marketing, online public relations. The choice is vast. To make this choice more comfortable, take the following steps:

define goals

allocate budget

determine your audience.  

In its turn, a digital marketing challenge determines the type of content the brand can use. Blog posts, articles, videos, stories etc. All these types prove to be more or less effective depending on the channel used to distribute them.

The use cases mentioned above prove the statement that application of data science brings numerous benefits to marketing campaigns of various brands. Considering the amount of data available today it is essential not just to freeze it but to use it for the benefit of the company.

Transformation of data into meaningful insights is crucial for decision making. Our list of top data science use cases in marketing reveals specific features of data application in this area and real positive effects it may cause.

Want to receive the best of our blog every single month?

From engagement statistics to content analytics to conversion metrics, data is a big part of most social media managers’ responsibilities. But that doesn’t necessarily mean you enjoy processing marketing data or drawing conclusions from it.

If data isn’t exactly your favorite part of the job, these marketing analytics case studies may change your mind.

Find out how marketing analytics helped three major brands grow their businesses—and you might develop a whole new appreciation for marketing data in the process.

What Is Marketing Analytics?

Marketing analytics is the process of collecting and evaluating metrics to understand how much value marketing efforts generate. With analytics, you can assess the return on investment (ROI) of anything from social media posts and ad campaigns to landing pages and native platform features.

For many organizations and their marketing team, marketing analytics are essential for improving offerings and driving growth.

Here are common goals you can achieve with marketing analytics.

Improving marketing campaigns

Some social media marketing campaigns are more successful than others. Analytics can help your organization pinpoint exactly what works. By analyzing metrics like engagement, click-through rate (CTR), conversions, and ROI, you can determine what resonates best with its audience. By using data science, you can craft a marketing strategy that gets you better results from your campaigns.

Decreasing expenses

Ineffective marketing campaigns, usability issues, and poorly optimized algorithms can all lead to dissatisfied customers and unnecessarily high retention costs.

By investing in marketing analytics, your organization can take steps to identify points of friction and reduce expenses.

Forecasting results

Reviewing past outcomes is useful, but forecasting the results your campaigns are likely to generate is even more valuable. With marketing analytics, you can model results and get a better sense of how marketing initiatives can impact growth over time.

Marketing Analytics Case Studies: Progressive Insurance

In the early 2000s, Progressive’s website was routinely considered one of the best in the insurance industry. When the insurance provider’s customers began switching to mobile devices a decade later, the organization aimed to develop a mobile app as effective as its desktop site.

But what did that mean exactly? And what was the insurance provider’s mobile app missing?

To determine what would make the mobile app more successful, Progressive pursued an in-depth analysis of the organization’s marketing data.

As Progressive Data & Analytics Business Leader Pawan Divakarla explains , the insurance provider’s analytics team has always sought insight into how customers are using the company’s tools.

In his words, “At Progressive, we sell insurance. But if you think about it, our product is actually data.”

After launching the mobile app, Progressive began looking for ways to optimize the user experience. As this Progressive case study explains, the organization aimed to streamline the login process and improve user satisfaction to meet its ultimate goals of increasing customer loyalty and new customer acquisition.

Because Progressive’s mobile app generated so much information, the organization needed data visualization tools for collection and processing. To analyze customers’ experiences and actions, the company opted to use a combination of Google Analytics 360 and Google Tag Manager 360.

This choice was a relatively simple one for Progressive because the company already used these tools to run A/B tests and optimize its website.

Using Google’s analytical tools to review the company’s mobile app would allow Progressive to understand what features to test and how to optimize the user experience across countless mobile devices and operating systems.

Progressive used the two Google tools for separate yet complementary functions:

  • With Google Analytics 360, Progressive could track user sessions and demographics. The company integrated BigQuery for more insight into user behaviors.
  • With Google Tag Manager 360, Progressive could easily implement tracking tags to measure various actions, conversions, and navigation patterns.

To get the insights the company needed to improve its mobile app, Progressive took a three-pronged approach:

User device data

First, Progressive aimed to identify which devices and operating systems were most common among the app’s user base. With this information, the company would be able to develop more effective tests for its mobile app.

App crash data

Next, Progressive wanted to analyze app crash data. The company planned to use Google Analytics 360 and BigQuery data to understand the cause for the crash and how users reacted when the app stopped working abruptly.

Login and security data

Finally, Progressive aimed to learn how users responded when failed login attempts locked them out of the app. The company planned to use Google Analytics 360 and BigQuery to see what actions users took. It planned to then test new prompts that would guide users more effectively.

Outcome of this marketing analytics case study

Using marketing analytics tools , Progressive was able to process customer behavior, identify appropriate tests, and implement successful solutions.

Here’s how each of the three approaches generated useful results that helped Progressive reach its ultimate acquisition and loyalty goals.

First, Progressive developed session-based reports that reflected the most common mobile devices and operating systems for the app’s user base. With those insights, the company identified which device and operating system combinations to prioritize for its mobile app tests.

As a result, the company reduced testing time by 20% for its mobile app—allowing the organization to find solutions much more quickly than its typical timeline would have allowed.

Next, Progressive reviewed the actions customers took right before the app crashed. The company pinpointed a server issue as the cause of a major crash that disrupted countless mobile app sessions.

Using this data, Progressive could address the server issue and prevent it from happening again.

Finally, Progressive created a custom funnel in Google Analytics 360 to evaluate users’ typical login path. After learning that many users who became locked out of their accounts never attempted to log in again, the company developed a workflow that provided better guidance.

The new workflow sends users to a Forgot Password page, which has increased logins by 30%.

Marketing Analytics Case Studies: Netflix

When companies take a digital-first approach to customer loyalty, they can collect an incredible amount of user data. With these marketing analytics, companies can improve their products, build better marketing campaigns, and drive more revenue.

As this Netflix case study shows, the online content streaming platform has leveraged its user data in a variety of helpful ways.

By using data to improve its content recommendation engine, develop original content, and increase its customer retention rate, Netflix has positioned itself far ahead of the competition.

With so much data to leverage, Netflix had wide-ranging goals for the company’s marketing analytics. However, all of the organization’s goals contributed to the company’s larger business objectives—which focus on customer retention.

Netflix aimed to go beyond basic user demographics and understand what customers want from a streaming platform—and what was likely to convince them to stay. With this knowledge, Netflix could create better products and services for happier customers.

Access issues, service outages, and platform flaws can all lead to unhappy customers and negative sentiment—which can cause customers to seek out an alternative solution.

By identifying problems early through marketing analytics, Netflix could improve its products and continue to innovate.

To work toward its customer retention objective, Netflix collected data from virtually every interaction with its 150+ million subscribers. The company then used marketing analytics tools to process this native data and evaluate everything from how customers navigate the platform to what they watch.

By creating such detailed customer profiles, Netflix could make much more personalized recommendations for each user. The more data the company collected, the more it could tailor its algorithm to suggest the ideal content to each individual viewer.

To better understand the platform’s users, Netflix collected such data as:

  • The devices viewers used to stream content
  • Day of week and time of day when users viewed content
  • Number of serial episodes viewers watched in a row
  • Whether viewers paused and resumed content
  • Number and type of searches users performed

Netflix also welcomed user feedback on content . The company incorporated these content ratings into their analysis to better understand viewer preferences.

According to the streaming platform, the Netflix algorithm is responsible for about 80% of viewer activity . The company has successfully collected relevant data and used marketing analytics to generate recommendations that encourage viewers to continue watching and subscribing.

The revenue metrics suggest that Netflix’s focus on marketing analytics has been hugely beneficial to the company. The company estimates that its algorithm generates $1 billion in value every year, largely due to customer retention.

In recent years, Netflix’s customer retention rate has far surpassed competitors like Hulu and Amazon Prime. Netflix has an impressive 90% retention rate , meaning the vast majority of viewers continue to subscribe to the service month after month. (In contrast, Amazon Prime’s retention rate is 75%, and Hulu’s is 64%.)

For Netflix, customer retention means more than happy viewers. It also means more data, a continually improving algorithm, and substantial business growth.

Netflix has emerged as the world’s most highly valued company, with a total valuation of over $160 billion. Netflix can continue to increase this valuation. It leverages its data by producing original media and recommending the ideal content to viewers every time they access the streaming platform.

Marketing Analytics Case Studies: Allrecipes

As the world’s biggest digital food brand, Allrecipes has 18 websites and more than 85 million users. But the brand also has plenty of competition from other food-focused apps and websites.

To stay ahead of other recipe sites and ensure that it continues to provide all the solutions that users want, Allrecipes relies on marketing analytics.

With marketing analytics, the digital brand can better understand the customer journey and analyze trends as they emerge. As this Allrecipes case study explains, the brand can expand its audience and attract even more lucrative demographics using these insights.

To continue to gain ground as the world’s top digital food brand, Allrecipes established several wide-ranging goals.

Some of the brand’s primary objectives included the following.

Improve user experience

With more than a billion and a half visitors across the brand’s sites every year, Allrecipes generates a ton of traffic. But the company needed a way to understand how visitors were using the site, so it could improve the user experience and gauge the health of the sites.

Increase video engagement

To take advantage of a demand for video content, Allrecipes had decided to invest heavily in video. However, the video production team needed strategic guidance. The brand needed to know what types of content would drive the most engagement.

Drive mobile engagement

To continue to meet the needs of its user base, Allrecipes had to look beyond its websites. As more and more people began using mobile devices to access the brand’s content, Allrecipes realized that the company needed to optimize its mobile app.

Inform product strategy

To promote new features and integrations or pursue partner programs, Allrecipes needed to know what its community wanted. Had they adopted the new integrations yet? Did they need new features to use the site or app more effectively?

Expand user base

Cooking and dining trends come and go, and Allrecipes needed a simple yet effective way to identify these developments.

By responding quickly to trends, the brand would be able to capture a larger user base, including elusive millennials.

Grow advertising revenue

Like many digital brands, Allrecipes has a native advertising program that allows the company to monetize its website. The company aimed to increase its advertising revenue, yet the organization didn’t want to compromise the user experience. To find the right partners to grow this program, Allrecipes needed deeper insights into its audience.

Although the brand’s goals were varied, the approach was relatively straightforward. To process marketing analytics from a wide range of channels, the brand opted to use Tableau, a business intelligence platform.

With Tableau, Allrecipes could establish a single platform for visualizing data from Adobe Marketing Cloud, Hitwise, and comScore. By linking Adobe Marketing Cloud to Tableau, the brand could pull in all of its website and marketing analytics. By linking Hitwise and comScore, the brand could source demographic data.

Using Tableau allowed Allrecipes to build custom dashboards and develop tailored reports to answer all of the brand’s questions. This tool also allowed the brand to pursue collaboration options across the organization.

In fact, departments ranging from marketing and design to product and finance contributed to the tool. Teams used Tableau Server to publish dashboards, creating a single space where stakeholders could visualize or analyze data.

With Tableau, Allrecipes was able to visualize the brand’s data successfully, enabling smarter decisions and making progress toward key goals. Here’s what the brand accomplished using marketing analytics:

Using insights from Tableau, Allrecipes was able to see how visitors typically used the site—including how they submit recipes, share content, and post links on social media channels. The organization then used this data to devise a plan for improving the site.

Knowing how visitors were already engaging with the site allowed the brand to make data-driven, goal-focused decisions.

With Tableau’s marketing analytics, Allrecipes found that out of all types of recipes, dessert typically generated more views and attracted more comments and photos. As a result, the brand opted to focus on this highly engaging niche, creating a separate video hub for dessert recipes.

To increase engagement on mobile devices, Allrecipes devised an A/B test that displayed the brand’s mobile site on all devices. Then the organization used the analytics to identify what drove interactions on mobile. The brand then used insights to improve the mobile site, including optimizing content and encouraging photo uploads.

Tableau’s data visualizations helped Allrecipes understand trends in its user community and respond to preferences more efficiently. Using these insights, the brand was able to promote integrations and features while gathering data for future product enhancements.

By using Tableau’s insights to process trends, Allrecipes was able to segment audiences for various recipe types, ultimately identifying millennial users’ interests and preferences. The brand was then able to create more content geared toward this growing user base—likely responding much more quickly than competitors could.

By tapping into real-time marketing analytics, Allrecipes was able to share popular recipe searches and trending content with its advertising partners during a recent holiday season. Advertisers could then create ads tailored to these interests, generating a better ROI and creating a more appealing experience for users.

Data Science in Marketing - Benefits and Challenges

Benefits and challenges of using Data Science in Digital Marketing

Without data science, digital marketing strategies would be hard to succeed.  Businesses can learn about the preferences and requirements of their clients using data science methods. The gathered data lets organizations identify customers and personalize their marketing campaigns to match their buying patterns, lifestyles, and interests. However, many marketers still lack the appropriate expertise, techniques, and technology support to effectively implement data science in marketing.

Some significant benefits of incorporating data science into digital marketing have been outlined below.

Digital marketers mostly deal with budget constraints. Every marketing team strives to get the best return on investment from the budget they have been given, and this is usually challenging to achieve. Effective budget consumption is difficult because numbers don't always meet the plan.

A data science team can develop a budget proposal that will more efficiently use the budget by looking at customers' buying habits. Many experienced digital marketers will find this approach useful for distributing their budget among various initiatives, channels, resources, and tools to maximize key metrics.

Data science and machine learning can identify the channels that give digital marketers adequate revenue. A data scientist uses a time series approach to analyze, study, and pinpoint the different lifts observed across several channels.

Additionally, this may be beneficial as it shows the marketing team which channel or sign generates precise and appropriate revenue.

Search engine optimization (SEO) is a strategy to increase website traffic, and data science quickly changes how people increase website traffic. Data scientists use search engine features by gathering, analyzing, and offering feedback on raw data. The goal of a data science team in this SEO is to eliminate guesswork.

Data scientists predict what's enabling them to get the desired results and how they can maximize their success, in addition to speculating how things work and how a specific activity influences the company's goals.

Digital marketers must choose the right approach for customers to get the most out of their online marketing operations across social media channels. To do this, they can develop a model for estimating the lifetime value of a consumer that can categorize consumers as per their presence.

 For instance, businesses might offer discounts and even referral vouchers to their best-value customers while adopting retention strategies for customers more likely to leave their audience.

Not every lead that a marketer acquires turns into a potential customer. The sales traffic and the department's performance will improve if digital marketer can segment their customers according to their needs.

Data science gives marketers the ability to create an intimidating lead scoring system. This system uses an algorithm to predict the conversion likelihood and appropriately segment the lead accounts.

Below are some of the top data science for marketing challenges you need to know to develop an effective marketing strategy. This will allow you to access and utilize the data you need to boost sales, retain consumers, and increase profitability.

One of the most common marketing data science challenges is a skill shortage – especially for small businesses. There are just not enough marketers with data science skills for marketing analytics due to the complexity and overall challenges of the field.

Marketers struggle to use raw data to support decisions due to their lack of analytical expertise. As a result, it will be challenging to use analytics to determine the effectiveness of marketing strategies. Additionally, without a clear return on investment, marketers are unwilling to raise their investment in a more effective marketing plan.

You can believe as a marketer that "the more data collection takes place, the better we know about the behavior of the audiences."

The problem with having too much raw data is that you often have too little information. Since there is an excessive amount of diverse information, the more data and fields collected, the less they match. As a result, the data will have "gaps." It will be challenging to transform all this raw data into actionable insights that can be used to drive business outcomes. As a result, you will possibly draw zero conclusions about your audiences' buying habits.

There is no universal marketing data science tool because each has special features that address every business's various and specific needs. Therefore, one must possess a solid understanding of marketing principles and all marketing data science tools and techniques to build effective marketing strategies. Without in-depth research on the tool or technology you intend to employ, you risk incurring extra expenses and the hassle of learning how to use it.

Lack of knowledge about reading and applying marketing data to increase business growth is one of the most common problems every marketing team faces. Marketers may keep detailed records of how many customers open their emails, watch their explainer videos, click on their media ads, and other events. Many marketers, however, still don't seem to fully understand the precise value of each piece of data and how it might support their business operations. In this situation, they have no idea how to use big data effectively and what to achieve.

Work on these data science project examples and get a step closer to your dream of becoming a data scientist!

Role of Data Science Algorithms in Digital Marketing

1. Clustering

Clustering is a machine learning algorithm for organizing data points into a single cluster.   The characteristics and qualities of data points in the same cluster should be similar. Likewise, the characteristics and qualities of the data points in various clusters should vary.

Clustering algorithm groups similar clients into the same segment and helps in effective customer segmentation. The clustering technique helps better understand customers in terms of static demographics and dynamic behaviors. Customers with similar traits often similarly engage with businesses; thus, businesses can optimize their marketing efforts by generating custom marketing strategies for each cluster or segment. Businesses can analyze these clusters to learn more about their customers and characterize them using various factors in the cluster analysis.

For instance, digital marketing teams can analyze and identify customer churn using K-means clustering to identify and categorize customers according to retention. They may identify and forecast retention rates for specific customer segments using variables like frequency of purchases, how recently the customer visited the business, average purchase per visit, etc.

2. Regression Models

Regression modeling is another method that can enhance marketing strategy by predicting a specific value for data that is crucial to an organization. This method is similar to classification, which forecasts if something will occur, but it differs because regression (also known as value estimation) forecasts the magnitude of an event. A regression algorithm can generate a statistical prediction for a situation like "How much of Product X will be used by Segment A" by considering similar customers and their past behavior.

Analyzing how much additional money you might be able to receive from a specific customer through cross-selling or up-sell prospects is an excellent application of regression modeling in marketing.

3. Classification

Classification modeling, or class probability estimation, is a great approach for identifying your best clients. These algorithms provide a solution to the question of whether or not something belongs in a particular category. For instance, "Will this group respond to our marketing offer likely or unlikely?" Several companies employ classification models and predictive analytics to analyze the effectiveness of their existing marketing strategy and channels and decide where to target their marketing budgets.

To create a classification model, you must split your collected marketing data, such as historical prospect and customer data, into two categories: replied and didn't reply ideal and non-ideal prospect, or customers and non-customers. This classifier enables the algorithm to be tuned to both the desirable traits of your best customers and the unfavorable traits of your less-than-ideal consumers. The final model can then "score" your current customer base and any upcoming new prospects for their propensity to convert or become customers.

Applications of Data Science in the Marketing Industry

Here are some of the top applications of data science in advertising and marketing.

1. Data Science in Marketing- Marketing Budget and Channel Optimization

Performance indicators are the basis for determining where advertising budgets should be invested. Data science allows you to create algorithms to help businesses automatically determine whether the campaign ROI is positive or negative. Data scientists employ data mining techniques to identify the combination of channels that produces the best return on investment. Additionally, data scientists decide which budgets should be allotted to each channel for you to maximize your revenue without wasting money.

Data science can also contribute to channel optimization by significantly identifying the channels benefiting marketers. Data science methods like market basket analysis present a much better understanding of the kind of customer a business is trying to acquire and the best channels to target customers. Moreover, these methods significantly improve the marketing message's efficiency. A data scientist can compare and characterize the types of distinct channels using a time series model. This can be useful because it reveals to the marketer which channels produce the ideal outcomes.

2. Data Science in Marketing- Customer Attrition and Loyalty Rating

At the top of the marketing funnel, data science helps target the right customers. In the middle, it can be used to predict customer behavior and learn how to engage with them. At the bottom, it can be used to retain customers and forecast the likelihood that they will make additional purchases. Furthermore, machine learning and data science algorithms can forecast churn rates, enabling businesses to develop more effective marketing initiatives focused on clients (e.g., discounts or incentives) who will likely stop interacting with the business shortly. This is especially crucial for business models involving subscriptions or recurring contracts.

3. Data Science in Marketing- Sentiment Analysis

The way customers feel when they first browse a business’s social media pages or website can have a big impact on how positively they perceive you. Reviews or comments made by others often influence this response. Applying sentiment analysis to access the clients' sentiments is crucial in ensuring that organizations have command over their reputations. Although this can be carried out manually, machine learning models significantly speed up and improve the efficiency of this data analysis.

Each social media post can receive a score based on the responses in the comments section by assigning certain values (negative, neutral, or positive) to individual words. The same technique may be used to analyze phone calls, Google reviews, and even email and email interactions. This can assist businesses in identifying the products, services, or social media marketing initiatives that generate the ideal responses from their list of potential customers and identify areas where customer service is unsatisfactory.

Explore Categories

4. Data Science in Marketing- Customer Segmentation

Customers are all unique individuals. Therefore, a one-size-fits-all approach is inefficient. Customer segmentation saves the marketers in this scenario. Marketers can segment data and classify consumers through statistical analysis. Customer segmentation is the process where marketers acquire data and group customers depending on how closely their characteristics match certain criteria. With this marketing strategy, an online marketer can identify groups of clients or prospects that are alike and distinct from one another.  

Data science makes it possible to define certain traits or variables that serve as the basis for this customer segmentation. Data scientists identify the factors that accurately characterize the various segments. Data scientists might, for instance, examine if specific website characteristics, such as Product Category or Brand, might be used as crucial factors for creating segments based on purchasing patterns.

Data scientists may employ certain machine learning algorithms to determine the potential value of each ideal customer segment and which products are most likely to attract them. 

5. Data Science in Marketing- Recommendation Engines

Online marketers utilize recommendation engines , another data science tool, to suggest products based on user behavior, purchase history, brand category, site search words, etc. This data science tool aims to show the appropriate product to the suitable client at the right time on a website. A strong predictive analytics system serves as the foundation for recommendation engines.

Collaborative and content-based filtering are the two alternative strategies based on either user behavior or the content of the products. In both scenarios, data scientists apply data mining techniques to classify the products in a way that will optimize their recommendations. The optimal scoring system for generating recommendations based on consumer behavior or content similarity is also established by leveraging data science methods.

6. Data Science in Marketing- Lead Targeting and Scoring

Not every lead ends up becoming a customer. However, if a marketer can accurately categorize customers according to their interests, many leads will result in customers and serve as examples for predicting customer conversion. Lead targeting and scoring involve predicting values for potential customers so that companies may optimize their interactions with them. When marketing departments reach out to these customers, data science tools can identify important variables (such as buying patterns) that can be combined to forecast the odds of a response or success. Data professionals use artificial intelligence and predictive analytics for advanced lead targeting and scoring, including variable selection and algorithmic modeling. Furthermore, data scientists integrate their insights with data mining to create tools and applications to help marketing teams make better choices and improve overall marketing efforts. 

7. Data Science in Marketing- Pricing Strategy

A marketer must have a smart pricing strategy that aligns client expectations with revenue generation without compromising them. Data science enables marketers to consider factors such as individual customer preferences, purchase history, market trends, and the economic situation, which affect customer pricing and buying intention. As a result, businesses can decide on reasonable pricing for their products and optimize their marketing campaigns. Additionally, data professionals provide data science solutions that automatically scan price changes on business websites so you can respond quickly as needed.

8. Data Science in Marketing- Real-time Analytics

Real-time analytics enable businesses to monitor and assess customer activity in real-time, providing relevant, meaningful insights just in time for customer conversion. Additionally, real-time analytics enable faster response times when your target customers change, saving you money and unnecessary marketing resources.

The two data groups with which real-time algorithms interact are operational and customer data. Operational data reveals the different choices and transactions that customers make. The demands and preferences of the customers are represented in the customer data. These real-time data help marketing campaigns be more effective by acquiring customer data, conducting tests in real-time, finding effective platforms, providing prompt responses, and improving customer experience.

Data Science is also being increasingly used in the public sector to help governments better understand and serve their citizens. Below is a case study in data science:

Chicago, Illinois, has been utilizing Data Science to analyze traffic data and enhance traffic signal timing. The initial timing of the city's traffic signals was based on a fixed schedule, which frequently led to long waits at junctions and worsened traffic congestion.

To address this issue, the city created the Adaptive Traffic Control System (ATCS), which employs Data Science to adjust the timing of traffic signals based on real-time traffic data. The system takes data from multiple sources, such as traffic sensors, weather sensors, and public transportation data, analyses the data with machine learning algorithms, and optimizes traffic signal timing.

The ATCS technology has been remarkably effective at reducing traffic congestion and enhancing traffic flow. The city of Chicago claimed a 16% decrease in total travel time and a 22% decrease in the number of intersection stops. In addition, the system has decreased pollutants and enhanced air quality by decreasing the length of time vehicles idle at crossings.

The effectiveness of the ATCS system in Chicago has prompted other cities to adopt similar systems. This is just one example of how the public sector is utilizing Data Science to improve the lives of inhabitants and make cities more efficient and sustainable.

Marketing Data Science - Case Studies from Airbnb, Lyft, Doordash

In this article we'll look at several case data science case studies from marketing optimization efforts at companies like Lyft, Airbnb, Netflix, Doordash, Wolt, Rovio Entertainment.

Drazen Zaric

Drazen Zaric

In my 10+ years in software I've made parts of MS Office, built data tooling and did data science for products with 100+ mil. users Here I summarize the best lessons from the industry.

More posts by Drazen Zaric.

In the first quarter of 2019, Airbnb spent $367 million on sales and marketing. When you think about this from a technical standpoint, two obvious problems come to mind:

  • How do you scale your marketing processes to be able to spend $300+ million per quarter on ads?
  • Once you have systems in place to spend huge ad budgets, what's an optimal way to allocate the money?

In this article we'll look at several case studies of data science in marketing, applied to optimize efforts at companies like Lyft, Airbnb, Netflix, Doordash, Wolt, Rovio Entertainment.

Summarizing articles from official blogs of these companies, we'll get a high level overview of marketing automation and then zoom in on the parts where data science and machine learning play their role.

If you read on, you'll find these three sections:

  • Marketing automation systems - what are they, what subsystems they comprise, where in the process is data science usually applied
  • Performance estimation - why estimating the performance of your campaigns is the fundamental problem in marketing analytics and what is the data science tool set used for this
  • Optimizing bidding and budget allocation - once your marketing efforts are at the scale of hundreds or thousands of concurrent campaigns, it's impossible to allocate you budget manually in an optimal way. This is where Marketing Data Science shines. We look at two simple algorithms for budget allocation, shared by DoorDash and Lyft engineers.

Marketing Automation Systems

In large and analytically mature organizations, the optimization piece usually comes as a part of a larger marketing automation system, but as we'll see it's not always the case. Allocating budgets manually but aided by data science can be hugely profitable and might be a good first step towards a fully automated workflow.

Before diving into details, let's look at high level architecture of an automated process for online marketing.

Generally, all advertising platforms involve a common workflow. You set up the ad creative (text, visuals), choose the target audience, set bidding budget and strategy. As a result of streamlining this workflow, marketing automation systems are very similar in their high level architecture. Usually, these systems comprise the following:

  • Data tracking system Track conversion events (customer signups, payment events, subscriptions, micro-transactions, etc).
  • Attribution system Connect conversion events with the user acquisition source. That is, for each user we want to know exactly the marketing channel and the campaign that brought them in.
  • Performance estimation system Let's say a campaign brought in 1000 users. We want to know if it paid off. We know how much we spent on it, but how do we know how much revenue the users will bring us over their lifetime. LTV and conversion modelling comes into play here.
  • Campaign management system Online ads are a very fertile field for variation testing and content generation. But even without testing multiple you variations of the same ad, companies typically target different segments in different ways, easily resulting in dozens or hundreds ads running simultaneously. Companies like Airbnb and Netflix invest heavily in systems that support ad creation and management ( Airbnb article , Netflix article ).
  • Automated bidding and budget optimization The largest ad serving platforms provide you with near real-time feedback on your ad performance. Connect this with the spend and projected LTV and you can get your ROI predictions and adjust budgets accordingly. With dozens or hundreds of campaigns and variations, the benefits of automation and optimization at this steps can be huge.

As we're interested in the role that data science can play in overall ad lifecycle, we'll focus on the two parts that tend to benefit the most from mixing in data science: 1) performance estimation and 2) automated bidding and budgeting.

Before diving in, it's important to understand the channel/campaign nomenclature. By channel we consider an advertising platform, such as Google AdWords, Facebook, Youtube, etc. A campaign is a single piece of advertising aimed at specific audience, according to segments available on the channel, with a preset starting and end time.

When evaluating marketing performance, we might want to look at investment and ROI at the level of a channel, a single campaign or a group of similar campaigns. We'll see how these different levels of granularity influence the amount and quality of available data, and in consequence how that determines the approaches that can be taken.

Performance Estimation

Ideally, for the purpose of marketing data science optimization we're interested in LTV and CAC (Customer Acquisition Cost) as the factor in the ROI equation: $$ROI=\frac{LTV}{CAC}$$

LTV modelling is a fundamental problem in business analytics and it is far from trivial to get it completely right. The exact models depend heavily on the type of business and the intended application. LTV models are generally more valuable if we can give good estimates very early in the user lifetime. However, the earlier we do it the less data we have at our disposal.

In Pitfalls of Modeling LTV and How to Overcome Them , Dmitry Yudovsky outlines several challenges that make it impossible for a cookie-cutter approach for LTV estimation to exist:

  • Machine learning approaches are sometimes completely inadequate. There might be lack of data necessary for long term LTV predictions. Also, even if we do have a large business with tons of historical data, there are cases when training models on year old data doesn't work well - maybe the product or the entire market is very different than a year or two ago.
  • Depending on whether we want to use LTV estimates for ad optimization, CRM efforts or corporate financial projections, we might have different requirements for model accuracy and cohort granularity at which we're making predictions (eg. single user, single campaign, group of campaigns, all users, etc.)

Of course the problem is not intractable, and there are several common approaches. We'll look at a few case studies found in tech blogs from DoorDash, Airbnb and Lyft Engineering teams.

In Optimizing DoorDash’s Marketing Spend with Machine Learning , Doordash data scientists present their approach, where instead of directly estimating LTV, they model conversion rates as a function of marketing spend. We'll see later how these cost curves help to neatly optimize budget allocation across channels and campaigns.

Experience (data) tells us that any marketing channel will reach saturation at some point, so we can model cost curves, ie. $Conversion=f(Spend)$ using a power function of the form $a\cdot Spend^{b}$.

data science marketing case studies

We can fit cost curves at any cohort level, and it's typically done at the granularity of a channel or campaign. Simply put, if for a given campaign we spent $x$ amount of money, and that brought us $y$ users, we have one data point, $(x, y)$.

However, when allocating budgets at a later stage, we might need to make decisions at the campaign level, which cause problems with insufficient amount of data. In the DoorDash Engineering article, Aman Dhesi explains this problem:

For some channels like search engine marketing, we have thousands of campaigns that spend a small amount of money every week. This makes the weekly attribution data noisy. Some weeks these campaigns don’t spend at all, which makes the data sparse. Using this data as-is will result in unreliable cost curves and in turn suboptimal (potentially wildly so) allocation.

At DoorDash they solve this problem by training separate models which use similar campaigns to fill in the gaps in the dataset with synthetic data. This approach brings with itself certain tradeoffs, described in the original article .

In a similar manner, as described in Building Lyft’s Marketing Automation Platform , data scientists at Lyft would fit an LTV curve of the shape $LTV=a\cdot Spend^{b}$. However, they incorporate an additional degree of randomness by modelling $a$ and $b$ as random variables and estimating their parameters $(\mu_a, \sigma_a)$ and $(\mu_b, \sigma_b)$ from historical data. This helps them implement an explore-exploit approach in the bidding step, by instantiating LTV curves after sampling $a$ and $b$ from their respective distributions. We'll revisit this approach briefly at the end of next section.

As described in Growing Our Host Community with Online Marketing , at Airbnb they face a problem stemming from the nature of their product and the market. When predicting LTV for an Airbnb home listing, two major problems are:

  • Ad conversions for hosts are a very rare event. This poses problems with building large enough data sets. It also influences data tracking and attribution, where these systems have to be as precise as possible in order not to lose or wrongly attribute any data points.
  • Time from ad impression (user seeing an ad) to conversion (home listed on Airbnb) can be very long, sometimes weeks. This is a problem if you want to optimize and re-budget your campaigns soon after rollout - you simply don't have enough data yet.

In the same post, Tao Cui describes the architecture of each part of Airbnb's marketing platform as well as the motivation for building the entire thing, along with choices of tech stack.

In another article dating from 2017, Using Machine Learning to Predict Value of Homes On Airbnb , Robert Chang describes how they use machine learning (ending up using XGBoost in production) to estimate LTV of each listing. Framing it as a typical regression problem, they use hundreds of features, such as location data, price with all the partial costs (eg. cleaning fee, discounts), availability, previous bookings, to predict revenue from a listing after some fixed amount of time (eg. 1-year revenue). If you're curious, the post also describes some of the pieces of infrastructure used by the system and gives a high-level code examples of training pipeline construction.

In Insights on the Pros and Cons of LTV-based Predictive Models an article from AppsFlyer, we can find a summary of pros and cons of the three common LTV modelling approaches for app-based businesses:

  • Retention/ARPDAU model If we have a fairly old and stable product with some historical data, we can leverage the fact that we know the shape of the retention curve and can fit a power curve to several early-retention data points. We also know the Average Revenue Per Daily Active User (ARPDAU) which tends to be stable over time for most freemium and micro-transaction apps (such as free to play games). With some math we can arrive at an estimate of the expected LTV using these two measures. For example, to estimate LTV by day 90 of user's lifetime we would use the following equation:  $$LTV_{90}=ARPDAU\cdot\sum_{d=0}^{90}retention[d]$$
  • LTV ratio model As a simple example, in order to get $LTV_{90}$ we'll use historical data to estimate the ratio $\frac{LTV_{90}}{LTV_{7}}$ and use the observed 7-day LTV to predict the 90-day LTV
  • Behavior driven/user-level models We'd use user-level features to train our favorite machine learning model for regression. This is the approach mentioned above in the Airbnb case.

The article further discusses pros and cons of each approach in depth, considering the type of business and the intended use cases for the LTV model.

Now, back to the big picture - we needed LTV estimation in order to predict performance of our marketing campaigns. Once we have satisfactory models in place we can use them to make decisions concerning ad budgets.

Optimizing bidding and budget allocation

Once we have the estimates of performance (ROI) for each campaign, we want to allocate our marketing budget across campaigns so that we maximize the total return on investment.

Depending on the degree of automation, we can use the data science-backed systems to either aid manual budgeting or to automate real-time bidding decisions in a fully automated system.

In the first case, we have a static problem where at some point in time we're looking at a set of channels/campaigns with their predicted ROIs. A set of sortable tables, visualizations and derived metrics can invaluably help campaign managers to optimize their efforts.

On the other hand, in a fully automated system, we can have algorithms bidding and deciding how to spend each dollar in an optimal way. Looking into articles from DoorDash and Lyft engineering teams, we learn about two variations of an approach that sequentially maximizes marginal value of each dollar spent.

In Optimizing DoorDash’s Marketing Spend with Machine Learning the proposed approach looks at cost curves for each channel/campaign, representing the function $Conversion=f(Spend)$. We note that the slope of the curve is monotonically decreasing as we increase spend, meaning that for each additional dollar spent our marginal value decreases - we get fewer conversions per $ spent.

data science marketing case studies

With such problem in place, in order to optimally allocate a fixed budget we can use a simple greedy algorithm:

  • For each channel/campaign $c$ set $spend\left[c\right]:=0$
  • For each \$ until budget is exhausted: 2.1. Find the channel/campaign $c_{best}$ with the largest marginal return (ie. the largest slope) at it's current spend. More formally: $c_{best}=\underset{c}{argmax}\left\{ \frac{\partial}{\partial spend}Conversion[c](spend[c])\right\} $ 2.2. Assign the next \$ to campaign $c_{best}$, ie. $spend\left[c\right]:=spend\left[c\right]+1$

Of course, models and budget allocations can (and should) be periodically updated using performance data obtained from the advertising platform APIs. That brings us to the approach relying on continuously experimenting and updating the model in an explore-exploit fashion.

In Building Lyft’s Marketing Automation Platform , a Multi-armed bandit approach is described. Instead of modeling $Conversion$, they fit an LTV curve, that essentially has the same power-function properties that we described above (monotonically decreasing slope). As mentioned in the previous section, they incorporate an additional degree of randomness by modelling $a$ and $b$ as random variables and estimating their parameters $(\mu_a, \sigma_a)$ and $(\mu_b, \sigma_b)$.

data science marketing case studies

Then they use Thompson sampling, a simple algorithm for Multi-armed bandit problem with a Bayesian model. An excelent introduction to Bayesian bandits and Thompson sampling can be found in Chris Stucchio's article from 2013 - Bayesian Bandits - optimizing click throughs with statistics .

In this article we've covered several case studies in using marketing data science to optimize online marketing with several different approaches. Sources vary in their depth and detail, but it's nevertheless inspiring to learn about all the different ways to solve common problems.
