Personalized product recommendations using AI to increase ROI

Imagine you visit an online store looking for a pair of sneakers. Before you finish typing "sneakers" into the search bar, the site already suggests models based on your size, your purchase history, and the colors you usually choose. Additionally, when you complete your purchase, it recommends athletic socks and a water bottle for the gym.

This is no coincidence: it's the power of AI in e-commerce, creating personalized customer experiences to boost sales and improve your shopping experience.

Personalizing product recommendations with AI has become one of the most effective strategies for increasing the ROI of online businesses, optimizing conversions, and building customer loyalty. Let's take a look at how it works, what its benefits are, and the processes behind this technology.

What is AI-powered e-commerce personalization?

AI-powered e-commerce personalization is the use of machine learning algorithms, natural language processing (NLP), and generative AI to deliver relevant product and content recommendations to each user in real time.

Amazon is one of the leaders in this practice. According to its corporate blog, Amazon uses generative AI to personalize product recommendations and descriptions in its online store. Based on each customer's shopping activity, its system creates targeted recommendations, such as "Mother's Day gift boxes" or "deals to improve your soccer game," rather than simply generic suggestions like "More like this."

It also dynamically adjusts product descriptions to highlight relevant attributes like "gluten-free" or "long-lasting battery," helping customers find exactly what they need more quickly.

How to use AI in e-commerce to personalize recommendations

Implementing AI in e-commerce for recommendations involves several stages:

Data collection

The platform collects information about user behavior: browsing history, previous purchases, searches, clicks, products added to cart, and even contextual data such as location and device.

Processing and analysis

AI algorithms identify patterns and segment users into groups with similar behaviors. This is known as audience segmentation.

Recommendation generation

Based on the detected patterns, the system suggests relevant products for each segment or individual user. Generative AI can even create personalized descriptions that highlight what matters most to each customer.

Continuous optimization

As the user interacts with the site, the system learns and adjusts the recommendations, making them increasingly accurate.

IBM confirms that AI-driven personalization is becoming more sophisticated and consumers expect it. In fact, a study by the IBM Institute for Business Value reveals that 71% of consumers expect personalized content and 67% are frustrated when they don't receive it. Furthermore, fast-growing businesses generate 40% more revenue through personalization.

Types of AI-Based recommendation systems

According to Shopify, there are three main types of recommendation systems that can be implemented to create personalized customer experiences:

• Content-based filtering: This approach analyzes product attributes (such as category, color, material) and user preferences. If a customer has previously purchased black running shoes, the system will recommend products with similar characteristics.
• Collaborative filtering: This model uses the collective behavior of other customers. If many users who purchased the same product as you also purchased a specific accessory, the system will recommend it to you.
• Hybrid filtering: It combines both of the previous methods, offering recommendations based on content and the behavior of other users to achieve greater accuracy and relevance.

Gymshark, for example, uses recommendation engines to suggest products based on customers with similar interests, creating a personalized experience that drives conversion.

Benefits of personalized AI recommendations for e-commerce

Implementing AI in e-commerce for personalization offers multiple advantages for businesses:

• Higher Conversion Rate: By displaying relevant products, customers find what they're looking for faster and are more willing to buy.
• Increased Average Order Value (AOV): Recommendations like "frequently bought together" drive cross-sells and upsells.
• Better Customer Retention: A personalized experience keeps users coming back, increasing brand loyalty.
• Marketing Campaign Optimization: Precise segmentation enables more effective campaigns, reducing advertising costs and maximizing ROI.

According to Shopify, 56% of customers return to a store after a personalized experience, which translates to more repeat sales.

Customer benefits

Personalization not only benefits brands, it also significantly improves the shopper experience:

• Time Savings: Customers don't need to search through hundreds of products; they find what they want in seconds.
• Relevance: Recommendations are tailored to their specific needs, increasing satisfaction.
• New Product Discovery: By seeing personalized suggestions, customers find products they didn't know they needed.
• Purchase Confidence: Clear, personalized descriptions build confidence when making decisions.

How to increase ROI with AI in e-commerce

For ecommerce personalization to have a real impact on ROI, companies should follow these best practices:

• Integrate data from multiple sources: Unite data from CRM, social media, and analytics to gain a complete view of the customer.
• Use generative AI to create dynamic content: Like Amazon, adjust product descriptions in real time to highlight what matters most to the customer.
• Measure and Optimize: Evaluate metrics like conversion rate, AOV, and customer retention to continuously fine-tune the recommendation engine.
• Automate campaigns: Personalize emails, push notifications, and ads based on the customer's purchase history.

The key is to understand that personalization is not a one-time project, but rather an ongoing process of learning and optimization that can become the main driver of growth for any e-commerce site.
