A review is someone’s evaluation of something. We support reviews and ratings for a wide range of schema.org types, including businesses, products, and different creative works such as books or movies.
Google displays the following types of reviews in search results:
- Critic reviews: A snippet from a longer review article that a single editor has created, curated, or compiled for a publisher.
- Review snippets: A rich snippet of a review or rating markup from a review website, usually an average of the combined rating scores from reviewers. Review snippets appear in Google Search results either under the search result or in the Google Knowledge Cards.
