A review snippet or star rating is a short excerpt of a review or a rating from a review website, usually an average of the combined rating scores from many reviewers.
When Google finds valid reviews or rating markup, we may show a rich snippet that includes stars and other summary info from reviews or ratings. In addition to the text of the review, a rating is an evaluation described on a numeric scale (such as 1 to 5).
Review snippets may appear in rich results or Google Knowledge Panels. You can supply ratings for the following content types (and subtypes):
- Book
- Course
- Event
- How-to
- Local business
- Movie
- Product
- Recipe
- Software App
