Machine Learning and Marketing

Machine learning is a form of artificial intelligence (AI) that enables software applications to become more accurate at predicting outcomes without being explicitly programmed.

Marketers use ML to understand customer behavior and identify trends in large datasets, allowing them to create more efficient marketing campaigns and improve marketing ROI.

For example, Netflix uses machine learning to enhance its recommendations algorithm, forecast demand, and increase customer engagement.

By leveraging customers' viewing history, the company gains powerful insights into customer preferences, enabling them to make relevant content suggestions.

How Machine Learning Can Improve Marketing

Machine learning can improve marketing in umpteen ways. Here are the most common use cases:

1. Gauge Customer Sentiment

Machine learning algorithms can automatically identify customer sentiment, encompassing positive, neutral, or negative opinions.

Initially, they gather textual data from diverse sources like customer reviews, social media mentions, feedback forms, or survey responses.

Subsequently, the data undergoes preprocessing and is labeled according to the corresponding sentiment. This allows marketers to gain insights into customer sentiment and make improvements based on feedback.

2. Personalize User Experience

Machine learning models can analyze user behavior and historical data to predict customer preferences. Marketers use this opportunity to create personalized offers for customers, such as product recommendations, promotions, or discounts.

Additionally, ML can curate content feeds based on user interests and send personalized reminders to customers.

3. Optimize Content Distribution Efforts

Machine learning can analyze the performance of different content distribution channels and offer optimization strategies.

By accessing historical data, it can determine the best time for posting and the optimal frequency of content distribution to avoid overwhelming the audience.

It can also identify the most effective distribution channels, allowing marketers to allocate their resources wisely and achieve maximum engagement alongside ROI.

4. Optimize Ad Targeting and Bidding

ML is revolutionizing targeted advertising.

By analyzing a vast amount of сustomer data, machine learning predicts customer behavior and groups users into segments based on shared traits and characteristics.

Marketers then use this data to tailor ads to those segments, connecting with target audiences that are more likely to engage with the ad.

5. Streamline A/B Testing Processes

A/B testing plays an important role in marketing, as it clearly shows what‘s working and what’s not.

ML helps automate A/B testing processes and make them more accurate. Real-time monitoring of the testing process reduces manual intervention and the likelihood of potential errors.

Furthermore, machine learning decreases the test duration, saving time and resources when one variation significantly outperforms the other.

15 Examples of Machine Learning and Marketing

Forrester forecasts that nearly 100% of enterprises will be implementing some form of AI by 2025. Two more years to go, but numerous companies have already successfully adopted AI.

Here are 15 examples from real-world companies that saw significant improvements after implementing machine learning.

1. Amazon increased its net sales by 9%.

Machine learning has long been an integral part of Amazon, one of the largest retailers in the world.

The ecommerce giant has been using ML for a variety of purposes, such as getting insights into customer behavior and analyzing browsing and purchasing history to provide personalized product recommendations.

These enhance the customer experience as users easily find new products that are similar to their previous shopping experience. Additionally, Amazon creates targeted ads for users based on demand forecasting.

According to its latest financial report, the company’s net sales increased 9% to $127.4 billion in the first quarter, compared with $116.4 billion in the first quarter of 2022.

2. Netflix became an industry leader due to its personalized movie suggestions.

One of the main reasons why Netflix services are popular is that they are using artificial intelligence and machine learning solutions to generate intuitive suggestions.

The company uses machine learning to analyze its customers’ movie choices and make relevant content suggestions. But how does it work?

When you browse their movie directory, their intelligent algorithms watch what kind of movies captivate you, where you click, how many minutes you keep watching the same movie, etc.

Then analyzing your viewing habits, Netflix curates a personalized movie/TV show feed for you. It’s a win-win.

3. Armor VPN predicted lifetime value and maximized user acquisition efforts.

Armor VPN is a consumer cybersecurity (VPN) software that wanted to create a solid user acquisition strategy to attract new customers. With limited marketing budgets, the owners didn’t want to go through a trial-and-error process.

Thus, they partnered with Pecan AI, a predictive analytics tool, to make strategic decisions with the help of predicted lifetime value (pLTV) models.

With the tool’s predictions, the client identified a 25% gap on average between the actual user lifetime value and what they expected users’ value to be.

This way, Armor VPN could create a more effective and data-driven strategy to fuel its user acquisition efforts.

4. Devex scaled its content creation processes and decreased costs by 50x.

Devex, based in Washington, D.C., is a major provider of recruitment and business development services for global development.

The company receives approximately 3000 pieces of text weekly, which require manual review by the content team. Eventually, only 300 of these pieces are deemed worthy and tagged accordingly.

Until recently, the evaluation was done manually, which took around 10 hours to complete. To automate the process, Devex contacted MonkeyLearn, a text analysis platform powered by machine learning models.

Devex built a text classifier that helped them process data and then tag if the text was relevant.

It resulted in 66% time savings, and the operation costs decreased by 50x, as less human interference was required.

To overcome this, Airbnb used machine learning to provide rough estimates to potential customers. The prices were based on different criteria such as location, size, property type, seasonality, amenities, etc.

Then, by performing EDA, they could understand how rental listings spread throughout the US.

In the final step, the company implemented ML models, such as linear regression, to generate estimates and visualize how prices change over time. It allowed them to create attractive marketing offers and win new customers.

After reviewing heat maps and session recordings, the team concluded that visitors were initially interested in the benefits section but needed more information.

Consequently, they redesigned the application page, resulting in a 43% increase in conversions.

7. Tuff achieved a 75% success rate on partnership proposals.

Tuff is an SEO marketing agency that achieved significant ARR growth in just three years. Initially, they struggled to create client pitches due to the lack of a reliable SEO tool for thorough competitor and keyword research.

5 Tips for Using Machine Learning in Marketing

Machine learning can be highly beneficial, but you should know how to use it effectively. Here are five tips for effectively leveraging machine learning in your marketing efforts.

1. Be specific with your marketing goals.

Since ML processes enormous data sets, you'll likely get loads of unnecessary data. You can easily avoid this if you clearly outline what you want to achieve.

Narrow down your marketing goals and group them into categories such as customer segmentation, ad optimization, conversion acceleration, etc. Start with small-scale experiments and iterate once you have some results.

2. Don’t stick with one ML model.

Experimenting with multiple machine learning models is essential. Different ML models have different capabilities, each with its pros and cons.

For maximum efficiency, you'll have to test different ML models so you can compare their performance objectively.

For example, one ML model can excel in a certain type of data task but might underperform in a different scenario.

3. Don’t become over-reliant on ML tools.

While machine learning can generate valuable insights, over-relying on it can be detrimental for marketers. ML models are still evolving, and they are not perfect and can't fully function without human expertise.

For maximum results, it's better to combine ML with human knowledge. Clearly define each role and set a healthy boundary of when to use ML and when to rely on human decisions.

4. Partner with data scientists.

Not everyone has in-house data scientist knowledge. If you‘re just starting out, it’s a good idea to collaborate with a data scientist to implement the right ML models.

Make sure to ask the machine learning experts to explain the limitations of ML models so you don't have unrealistic expectations.

5. Respect data policy and be transparent.

AI and ML tools pose a threat to data breaches and privacy concerns.

Since customer data is vulnerable, you'll need to make sure you comply with data privacy regulations. Avoid unethical usage of customer data and be transparent.

These are crucial to building trust with your customers.
