A product recommendation system is one of the most effective ways to extract more revenue from the same e-commerce traffic. Showing the right product to the right visitor raises average order value (AOV), conversion and discovery. This guide covers the parts of an e-commerce recommendation engine and how to build them with CollectAction modules.
Why product recommendations work
Most visitors don't fully know what they're looking for; putting relevant products in front of them eases both discovery and purchase. Cross-sell (complementary) and upsell (higher model) recommendations noticeably raise the revenue from a single visit.
Similar and complementary products
The Similar Products module shows relevant alternatives and color options on the product page; Shop the Look raises basket value with outfit/complementary selling. Together they form a strong cross-sell layer.
Popular and recently-viewed rows
Popular Product Recommendation and Recently Viewed Products sliders ease discovery on the homepage and category pages and quickly bring visitors back to items they were interested in.
Personalized recommendations
With Most-Reviewed by User Interest you show each visitor a high-social-proof storefront matched to their interest category. This personalization directly feeds conversion.
Live recommendations with AI
DialogTab AI Chatbot recommends products, offers complementary items and answers questions in chat, turning your recommendation engine into a 24/7 live sales advisor.
Step by step to set up a recommendation system
- Show similar and complementary items: Add Similar Products and frequently-bought-together to the product page to start cross-selling.
- Enable popular and recently-viewed rows: Publish Popular Products and Recently Viewed sliders on the homepage and category pages.
- Personalize: Dynamically show the most-reviewed products in the user's interest category.
- Recommend live with AI: Use the AI chatbot to recommend products and complementary items in chat to close conversion.
