You can add a section to your product pages that displays an automatically-generated list of product recommendations. Displaying recommended products to customers makes it easier for them to discover new products, and can help to increase online store sales.
Before you add product recommendations to your theme, it's a good idea to get familiar with the following:
Recommendation logicAnchor link to section titled "Recommendation logic"
The algorithm that identifies recommended products predicts the most relevant products based on the product a customer is interacting with. The criteria that the algorithm uses depends on a merchant's online store, as well as their plan, however there are the following criteria in general:
- Purchase history - Finds products that have historically been purchased together.
- Product description - Finds products with similar descriptions.
- Related collections - Finds products from collections that the current products is part of, excluding collections with handles
Merchants can use the Shopify Search & Discovery app to customize product recommendation and search results, which can impact results from storefront search and the Ajax Product Recommendations API. To learn about how these results can be impacted, visit the Shopify Help Center.
Requirements and limitationsAnchor link to section titled "Requirements and limitations"
The recommendation algorithm criteria is listed above. However, the criteria that's used depends on a merchant's online store and plan. The following outlines which criteria is used, and when:
|Merchants with less than 7000 products published to the online store, and an English storefront.|
|Purchase history only||Merchants with less than 7000 products published to the online store, and a non-English storefront.|
|Related collections||All merchants when purchase history and product description recommendations aren't available.|
In addition to the above, there are also the following limitations:
- The recommendation algorithm doesn't use orders that have been imported from another store or ecommerce platform to generate product recommendations.
- Products that are out of stock, or set to a price of 0, and gift cards, aren't included in recommendations.
UI guidelinesAnchor link to section titled "UI guidelines"
The following best practices can help to make sure that you're displaying recommended products in a way that improves the customer experience:
- The recommendation algorithm associates up to ten products per individual product, in order of relevance. For example, the first recommended product is more relevant than the tenth recommended product. For this reason, it's a good idea to limit your recommendations to four products per product page to promote only the most relevant recommendations.
- Make sure that you load the proper image size for the product card.
- Use phrases such as “You may also like” for the section header to explain to your customers why you're displaying the recommended products.
