Exploring Machine Learning in Digital Marketing with Examples
Vlada Malysheva, Creative Writer @ OWOX
A couple of decades ago, the first thing that came to mind when you heard the words “artificial intelligence” was likely the rise of machines and the Terminator with a sawed-off shotgun. Today, this term has rather positive associations. Almost everyone encounters machine learning in ordinary life. For example, you might communicate with a chatbot on a website, be shown promotional offers corresponding to your hobbies, or set up a spam filter in your email service.
For marketers, machine learning is an opportunity to make crucial decisions based on big data quickly. In this article, we’ll talk about what decisions you can make based on big data.
Note: This post was originally published in August 2020 and was completely updated in January 2024 for accuracy and comprehensiveness.
What is machine learning?
Let’s start with a little terminology. According to Wikipedia, machine learning (ML) is a class of artificial intelligence methods characterized by their not providing direct solutions to problems but rather training systems to apply solutions.
There are many methods of machine learning, but they can roughly be divided into two groups:
learning with a teacher
learning without a teacher.
In the case of learning with a teacher, a person supplies the machine with initial data in the form of situation–solution pairs. The machine learning system then analyzes these pairs and learns to classify situations based on known solutions. For example, a system can learn when to mark incoming messages as spam.
In the case of learning without a teacher, the machine receives unsorted information — situations — without solutions and learns to classify those situations based on similar or different signs without human guidance.
Machine learning in Digital Marketing
Digital Marketers use machine learning to find patterns in user activities on a website. This helps them predict the further behavior of users and quickly optimize advertising offers.
What is the potential of behavioral data of the users?
In psychology, a pattern is a particular set of behavioral reactions or a common sequence of actions. Therefore, we can talk about patterns with regard to any area where people use templates (which is most areas of life).
Consider the example of a pattern used on websites. If the user isn’t interested in the offer in the pop-up window shown below, they can close this window by:
- clicking on the X sign
- clicking No thanks
- clicking anywhere on the site that’s outside the pop-up window.
In addition to these three actions the user can take, the pop-up window will close on its own after a certain period of time.
So we get four possible user actions:
- Click X — Can be true/false
- Click No thanks — Can be true/false
- Click past the pop-up — Can be true/false
- Pop-up viewing time is 5 seconds
When hundreds of such parameters are collected, the collected data gains value because it contains behavior patterns and dependencies. It hides the enormous potential of behavioral data, allowing us to supplement user data with the missing parameters based on the data we already have for other users.
For example, the simplest way to define a target audience is by gender and age. But what if users fill out this data only in 10% of cases? How can you understand how many of your website users fall into your target audience? Patterns of behavior can help.
You can use gender and age data from 10% of users to determine patterns specific to a particular gender and age. Then you can use these patterns to predict the gender and age of the remaining 90% of users.
Having complete data about gender and age, you can now make personalized offers to all website visitors.

Why machine learning is effective in marketing
The role of machine learning in marketing is to allow you to make decisions based on big data quickly.
The algorithm for the work of marketers is as follows: Marketers create hypotheses, test them, evaluate them, and analyze them. This work is long and labor-intensive, and sometimes the results are incorrect because information changes every second.
For example, a marketer will need about four hours to evaluate 20 advertising campaigns considering 10 behavioral parameters for five different segments. If such an analysis is carried out daily, the marketer will spend precisely half their time assessing the quality of campaigns. When machine learning in digital marketing is used, evaluation takes minutes, and the number of segments and behavior parameters is unlimited.
With machine learning, you can respond faster to changes in the quality of traffic brought by advertising campaigns. As a result, you can devote more time to creating hypotheses rather than to carrying out routine actions.
The value of your results depends on the relevance of the data on which the analysis was conducted. As data becomes obsolete, its value decreases. A person simply can’t process the volumes of information that are collected every minute by analytical systems. Machine learning systems can process hundreds of requests, organize them, and provide results in the form of a ready answer to a question.
Key benefits of machine learning in marketing:
- Improves the quality of data analysis
- Enables you to analyze more data in less time
- Adapts to changes and new data
- Allows you to automate marketing processes and avoid routine work
- Does all of the above quickly
Examples of machine learning in marketing
Machine learning is transforming marketing through data-driven insights and automated decision-making, enhancing customer understanding and campaign effectiveness. In the following sections, we'll explore specific examples of machine learning in digital marketing:
1. Customer Lifetime Value Prediction

How this data is used: To engage at-risk customers with retention strategies, special offers, or personalized communications.
Result: Reduced customer turnover, sustained revenue streams, and insights into potential areas of improvement.
Examples: Verizon, a telecom giant, could predict churn by examining factors like call drop rates, customer service interactions, and changes in monthly bill amounts. By identifying customers who exhibit behaviors indicative of churn, they can proactively engage them with targeted promotions, personalized offers, or service improvements to retain their business
4. Customer Segmentation
Essence: Grouping customers based on shared characteristics, behaviors, or preferences.
What it predicts: Which segment does a particular customer belong to?
How this data is used: To tailor marketing messages, offers, and product recommendations for different segments.
Result: More targeted and personalized marketing, leading to better customer engagement and increased sales.
Examples: Netflix employs machine learning to categorize its audience according to their watch history, favorite genres, frequency of streaming, and device preferences. This enables Netflix to refine content suggestions, and craft targeted marketing strategies for diverse user groups.
5. Predictive Analytics
Essence: Anticipating future outcomes based on historical and current data.
What it predicts: Potential future events such as sales trends, customer behaviors, or market changes.
How this data is used: To make informed decisions, prepare for future demands, and optimize strategies.
Result: Proactive business decisions that align with anticipated market needs.
Examples: Using predictive analysis, Walmart refines its store inventory planning approach. By scrutinizing historical sales patterns, factoring in seasonal changes, and integrating insights from local events and promotions, the retailer optimizes its stock levels, adeptly reducing excesses and safeguarding against product deficits.
6. Chatbots and Virtual Assistants
Essence: Automating customer interactions and service requests.
What it predicts: The intent and context behind a user's question or statement.
How this data is used: To provide relevant responses or actions.
Result: Quick, consistent, and scalable customer support or engagement.
Examples: Google Assistant doesn't just respond to queries; it uses machine learning to understand context, user preferences, and even nuances in voice tone. This continuous learning allows it to provide more accurate and personalized responses over time.
7. Email Marketing Optimization
Essence: Enhancing the effectiveness of email campaigns.
What it predicts: Best send times, optimal content, and target audience for email campaigns.
How this data is used: To send emails with higher open rates, click-through rates, and conversions.
Result: Improved engagement and ROI from email marketing campaigns.
Common algorithms for this purpose: Random Forest.
Examples: Mailchimp doesn't only send emails. Analyzing metrics like open rates, click-through rates, and conversion rates can suggest optimal send times, content tweaks, or audience segmentation to ensure the best engagement for each campaign.
8. Ad Targeting
Essence: Displaying the most relevant advertisements to users.
What it predicts: Which ad a specific user is most likely to engage with?
How this data is used: To place ads in front of the most suitable audience.
Result: Higher ad engagement, click-through rates, and conversion rates.
Examples: Nike collaborates with platforms like Facebook and Instagram to launch its new shoe. These platforms use machine learning to analyze user interests and behaviors, pinpointing long-distance runners. Nike then delivers personalized ads highlighting the shoe's benefits to this targeted group, resulting in increased engagement and efficient ad campaign performance.
9. Sentiment Analysis
Essence: Gauging public sentiment from text data.
What it predicts: Positive, negative, or neutral sentiment of a given piece of text.
How this data is used: To understand customer opinions, feedback, and overall brand perception.
Result: Informed strategies that address customer concerns and leverage positive feedback.
Common algorithms for this purpose: NLP.
Examples: Using machine learning, platforms like Yelp can automatically categorize user reviews based on their sentiment. By parsing the text, Yelp swiftly discerns whether a review leans positive, negative, or neutral. This approach not only streamlines the user experience by highlighting prevailing sentiments but also offers businesses a consolidated view of customer feedback, facilitating more effective responses.
10. Website Content Optimization
Essence: Dynamically adjusting website content based on user behavior.
What it predicts: Content or layout that a specific visitor is most likely to engage with.
How this data is used: To personalize the website experience for individual visitors.
Result: Higher engagement, lower bounce rates, and improved conversion rates.
Examples: Online platforms like The New York Times utilize machine learning to enhance user experience by tailoring content displays. The site can make informed decisions by tracking and analyzing user behavior, like their reading preferences and frequency. If a user frequently engages with tech articles, the algorithm ensures those topics are more prominently showcased on their homepage or suggested articles list. This results in a more personalized user experience, encouraging longer site visits, increased engagement, and greater loyalty to the platform.
11. Attribution Modeling
Essence: Determining the impact of different marketing touchpoints.
What it predicts: The contribution of each touchpoint to a conversion.
How this data is used: To allocate budget and focus on the most impactful marketing channels.
Result: Optimized marketing spending and strategy.
Examples: Airbnb aims to understand the effectiveness of its diverse marketing channels in driving bookings. Through this method, they can trace the entire customer journey, from an initial touchpoint, such as a Facebook ad, a Google search result, or an email campaign, to the final booking. This insight helps them optimize their marketing budget by focusing on the most impactful channels. Tools like Google Analytics assist businesses in comprehending the customer's path by showcasing the influence of various touchpoints, whether they're search ads, display ads, or other campaigns, in achieving desired conversions.
Don't just guess.

Machine learning in attribution
Why is machine learning in digital marketing needed, and how does it help you solve the attribution problem? This is a topic for a separate article (which we’re already preparing).
In this article, let’s figure out at what level decisions are made using attribution. We’ll compare these levels based on several criteria:
The level itself
Types of decisions made
Attribution models most often employed
Levels at which attribution-based decisions are made:
1. Vision Level
Who: A company’s vision is formed by its board of directors, CEO, and marketing director.
When: Quarterly, yearly
What: Vision-level decisions are associated with investments in the brand and balancing budgets between online and offline.
How: The tools used to make such decisions are market research and consultants.
Model: There’s rarely a place for classical data-based attribution models since the data on which decisions are based is not digitized enough.
2. Strategic Level
Who: Strategic decisions are made monthly by marketing and e-commerce directors.
What: These decisions are devoted to allocating the budget between channels and defining the top-level KPI.
How: The tools that help in making strategic decisions are Visual IQ, OWOX BI, or casual models.
Model: Here, the business uses data-driven attribution by GA4, variations on the theme of the Shapley value and Markov chains, or machine-learning funnel-based attribution. At this level, it’s important to understand the mutual influence of channels and make strategic decisions on their development.
Examine the advantages and disadvantages of popular attribution models, ranging from standard ones to Markov chains, Conversion Lift, and Machine-Learning Funnel Based models.
3. Tactical level
Who: Usually, tactical decisions are made weekly or even more frequently by the manager of paid traffic acquisition.
What: Budget allocation occurs between campaigns and ad sets, and decisions are aimed at clarifying KPI and campaign goals.
How: For making tactical decisions, you can use Google Sheets or OWOX BI.
Model: Often at this level, specialists use standard attribution models
The peculiarity of this stage is that the budget for a channel has already been allocated. So at this point, it’s important to understand what campaigns to spend it on, control the results, and quickly turn off inefficient campaigns.
4. Execution Level
Who: Bid manager
When: Nearly in real-time
What: This is when the decision to evaluate the contribution of a particular announcement or keyword occurs in close to real-time.
How: Such decisions are typically made inside advertising services (Google Ads, Facebook Ads).
Model: In fact, the customer doesn’t care what optimization mechanisms are used here, as they look at the results of each service separately.
As you can see, machine learning in digital marketing is most useful for strategic and tactical tasks. Sometimes, it’s also applied at the execution level, but the general trend is that advertising systems develop fast and have a lot of data. The internal algorithms used in these systems to manage advertising campaigns produce better results than an external model based on machine learning.
The reason is that to apply machine learning in marketing, it’s necessary to export large amounts of data from the advertising service quickly and then quickly import results back. Technically, this is a difficult task to solve on an industrial scale. Therefore, at the execution level, marketers tend to rely on internal algorithms for optimizing advertising services.
To use machine learning to solve tactical and strategic problems, you need to ensure the completeness of your data. You can do this with OWOX BI.
