# Related products

Related products are products that are similar to a selected product. You can display potential substitutes to help customers discover other similar products they might like.
## How to add the Related products to your product page
Steps
1. In the theme editor (**Customize**), open the template selector
2. Select **Products**, then **Default product.**
3. On the left-side bar, add **Related products.**
4. Make necessary changes **> Save.**
You can only add **one Related products section per product template**.
You can adjust the elements based on your needs to display the recommendation section such as heading, number of products to show, per row, etc. in the section settings.
## Automatically generated product recommendations
Related product recommendations are automatically generated for each product in your store. When you're customizing recommendations for a product in the Search & Discovery app, you can see a preview of the generated recommendations.
Shopify has built-in strategies to adjust these product recommendations based on products that are commonly purchased together, have a similar product description, or products in related collections. Each strategy has its own requirements in order to be used:
* Purchase history: The product needs previous sales to assess buying behavior.
* Product description: Only available to merchants with an English storefront.
* Related collections: Used when recommendations based on purchase history and product descriptions aren't available.
It's not possible to edit the generated product recommendations, but you can [add your own recommendations](https://help.shopify.com/en/manual/online-store/search-and-discovery/product-recommendations#create-product-recommendations) manually.
The generated recommendations for a product change frequently. It is common to have different recommendations when you revisit a product page as Shopify suggests new products that might be more relevant to shoppers. The product recommendations previewed in the Search & Discovery app will often be different than storefront for this reason.
