How to use review & rating schema markup
Review schema attaches a rating to an item so search engines can display star ratings — the eye-catching ⭐ ratings that boost click-through rate. This tool generates both a single Review and an aggregateRating summary, attached to the item type you choose (Product, LocalBusiness, Book, Movie, Course or SoftwareApplication).
A valid Review needs an author and a reviewRating with a ratingValue. The aggregateRating needs a ratingValue plus a reviewCount (or ratingCount). This is the core of any schema markup for reviews.
Important: only add review or rating markup for ratings that are genuinely collected and shown on the page. Self-serving or fabricated ratings violate Google's guidelines and can trigger a manual action that removes all your rich results.
Where star ratings can appear
Review snippets are supported on specific content types — not on a whole website or organization. Attach ratings to the actual thing being reviewed. Pair this with the Product generator for ecommerce, or the Local Business generator for a storefront. Validate the result with our schema markup validator.
