Review Schema Generator

Generate Review and AggregateRating JSON-LD for products, books, courses, software and more to earn star ratings.

Runs instantly in your browser — results update as you type.

How do I add review stars (Review schema) to my page?

Choose what is being reviewed, enter its name, the rating and the reviewer, and optionally the total number of ratings and their average. The generator writes valid JSON-LD — a Review with itemReviewed, or the item with AggregateRating — that you paste into the page so Google can show star ratings.

Google’s rules for review snippets

  • The review and rating must be visible on the page.
  • Use a real author name — not "Admin" or a company slogan.
  • No self-serving reviews: a business cannot mark up reviews about itself on its own LocalBusiness or Organization pages.
  • Supported types include Product, SoftwareApplication, Book, Course, Recipe, Movie, Event and more.

After publishing, test the page with Google’s Rich Results Test.

Frequently asked questions

Review or AggregateRating?

Use Review for one critic review; add AggregateRating when you show the average of many user ratings.

Are stars guaranteed?

No. Valid markup makes a page eligible; Google decides whether to show stars.

Is it free?

Yes.
