How to add related products to product page Shopify Tutorial
So what we need to do is to come to the theme section in the online store, go to the "Customize" option, click on the upper menu and select "Product pages". In this section, you can see there's a product recommendation option, let's go to this option, tick on the recommended product (you can change this thing if you want) and save it. If we just disable this option, the deleted product option will not be shown. Now, if your theme is not having this option, what do you need to do? There are two options available; in the first one you can change your theme as per the guidelines of Shopify or you can add an app for it. To change your theme go to "https://help.shopify.com/en/themes/customization/products/features/recommend-related-products", in this page there's a step by step overview that shows you how to change your theme to enable the option of the related product. In the other option, you should go to the product page, click on product.liquid and you should follow these steps; once you've done, you can select your theme, there is a code that you must copy and paste it in the relevant pages and once it is done, you should get an option like this. There's a third option in which you can add some app to enable your relative product option on the product page. I found this quite a good app, so once you have installed it, you just need to edit settings if you want to, and it will come as the related product into your product page. Here's one example store, let's have a look. This is the product page and after the product description is complete you can see the related product.
