As an online retailer, you want to do everything you can to increase your sales and improve your business and customers' shopping experience. One way to do that is by cross-selling. Cross-selling involves recommending related products to customers that complement or enhance the products they are currently viewing or purchasing.

By suggesting complementary or similar items to your customers, you can encourage them to make additional purchases and boost your average order value. One way to implement this method of cross-selling is by adding a related products section on your Shopify store.

This Shopify related products section displays products that are related to the item the customer is viewing, providing them with additional options and increasing the likelihood of a purchase.

In this article, we'll walk you through the steps of adding related products to your Shopify store and offer tips for making the most of this feature.

What are Related Products?

Related products are items that are related or complementary to the product a customer is currently viewing. For example, if a customer is looking at a pair of shoes, suitable product recommendations for related products might include shoe care products, socks, or other items that match the customer's style or interests.
Product recommendations influence buying decisions primarily because it helps consumers discover products they didn`t know about and didn`t know they even required.

Nevertheless, product recommendations like the ones you see on Sephora, Amazon and other e-commerce websites are becoming more ordinary, and it’s because of one reason: they seem to work.

According to a report by Barilliance, product recommendations account for up to 31% of eCommerce site revenues. Also, displaying related product recommendations can increase conversion rates by 550%. Sounds attractive?

By suggesting related products, you can:

  • Increase the chances of customers making additional purchases.
  • Encourage customers to explore your store further.
  • Boost your average order value.
  • Enhance the customer experience.
