Star ratings in search results catch attention. Google shows them only for certain content types and only when rules are followed.
Eligible content
- Product pages with genuine customer reviews.
- Recipes, books, courses, software and some other types.
Limits for local businesses
Google generally does not show review stars for a business’s reviews of itself when marked up on its own website (self-serving reviews). Local businesses’ ratings appear through Google Business Profile instead.
Requirements
- Reviews must be genuine and visible on the page.
- Correct schema for the product or item; generate product markup with our product schema generator.
- Aggregate rating values must match the reviews shown.
No guarantee
Even with valid markup, Google decides whether to show stars.
