SEO-friendly review scores
Go to the app store to install Product Reviews for Shopify
One of the most compelling features of the Product Reviews app is its support for Google microdata, sometimes referred to as rich snippets or structured data.
Product Reviews automatically adds an aggregate review score that appears in your search results on Google and adds a powerful way to increase traffic from organic searches:
Google doesn't allow microdata information to be included in AdWords or Product Listing Ads. Your aggregate review scores will appear only in your organic search results. Ultimately, Google decides what data to display, which means your data might not show up 100% of the time.
