pleents. review for Shopify Search & Discovery

Your theme will need to have sections to show related product recommendations and complementary recommendations for online shoppers to see them. This is described in our public documentation here: https://help.shopify.com/en/manual/online-store/themes/customizing-themes/add-product-recommendations. If you're able to: reach out to your theme's developer and ask for their help in making sure the theme can show these types of recommendations. You'll see these theme sections from the Online Store's theme editor if they exist. You can also check it out in any of the themes from Shopify's Theme Store as they come with product recommendation sections.
