What is Shopify Product Reviews?
The Product Reviews app supports Google microdata (sometimes referred to as "rich snippets" or "structured data"). The app automatically adds an aggregate review score that appears in your search results on Google, which helps to increase traffic from organic searches.
Using the Product Reviews app
Go to the app store to install Product Reviews for Shopify.
After you've installed the Product Reviews app, you can add review forms to your product pages, and review score badges to your product and collection pages.
