Product review schema can be extremely beneficial to have injected onto your product page. Having this schema can allow Google to show the star rating on the product page in organic search results, as seen in the image below:
Eligibility for Product Review schema is determined by:
Do I have Product Reviews as part of my Shopper Approved account?
Have I met the Google requirement for product review syndication?
You do not have existing schema or your existing schema is in JSON-LD format
Once these have been met, you can have Schema injected from the product page settings.
