Product recommendations is a section that you can add to your product page. Its purpose is to display recommended products based on a recommendation algorithm to entice your customers to add more items to their carts.
To locate Product recommendations, open your Theme Editor, go to a Product page template, and add the Product recommendations section.
How does the recommendation algorithm work?
The algorithm identifies recommended products based on data about products that were purchased together and products with similar descriptions. It uses this data to provide a mix of those related products as recommendations for a given product.
In cases where purchase or product description data aren't available for a given product, products from a related collection are shown.
The algorithm uses the collection in the URL from which the request to the API endpoint originated, and pulls other products from that collection. If the product doesn't have a collection URL, then the recommendation algorithm finds collections that include the product and pulls other products from those instead (excluding collections with handles all and frontpage).
Want more control over your product recommendations?
Shopify’s Search & Discovery app will allow you to customize the products that are shown alongside your products. Any products added under the Complementary products will be shown in the corresponding block on the product form. Any products added to Related products will display in the Recommended products section
