Woocommerce recommendation engines

Table of contents :

One of the best technologies to boost sales for e-commerce today are recommendation systems. But how could you add a recommendation engine to your woocommerce website?  You’re at the right place. First we will define what recommendation engines are, then we can establish strategies and solutions to add recommendation engines to Woocommerce.


What is a recommendation engine?


A recommendation engine, also called a recommender system, will suggest (or recommend) items that it predicts users will be inclined to view or buy. These predictions are based on patterns of users’ past behaviors and preferences.


This technology is based on personalization and is closely related to personalized search.


What are the benefits of a recommendation engine for Woocommerce?


Recommendations greatly boosts sales (conversions), user engagement and product discovery. This boosts sales because the items that the visitor will browse through have been tailored to their tastes, but also boosts user engagement since they don’t have to search for the interesting items, instead they passively receive a constant stream of relevant content.


It will also ensure that all your products are visible to the visitors, rather than being buried deep within multiple pages of pagination.

Recombee is an AI recommender that provides personalized search and recommendations (and even email). You can integrate it with an easy to use PHP client. You could check out our guide on how to build a Recommendation system using Recombee.

This is a more specialized recommender since it only offers personalization. No simple keyword search , facets (filters) or other things.

It is also probably the most affordable solution since it’s free tier offers lots of features and very generous limitations (up to 100 000 recommendations per month for free).
