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.
To participate, implement the markup, follow the guidelines for either critic reviews or review snippets, and register your interest in the pilot.
