Rich Snippets - Webmaster EDU

Reviews

New! schema.org lets you mark up a much wider range of item types on your pages, using a vocabulary that Google, Microsoft, and Yahoo! can all understand. Find out more. (Google still supports your existing rich snippets markup, though.)

When review information is marked up in the body of a web page, Google can identify it and use it to understand and present the information on your pages. Review information such as ratings and descriptions can help users to better identify pages with good content. (Learn more about rich snippets for Local Search.)

Usage guidelines

The goal of a review rich snippet is to provide users with review information about a specific product or service, such as the star rating (1 to 5 stars) and the name of reviewer(s).

The following guidelines apply to review snippets:

  • When using review markup, the main topic of the page needs to be about a specific product or service. For example, using review markup on a page containing multiple products is not supported.
  • Review of adult-related products or services are not supported.
  • If the markup contains a single review, the reviewer’s name needs to be a valid name (Person or Organization). For example, “50% off until Saturday” is not a valid name for a reviewer.

You can mark up either individual reviews (for example, an editor's review of a product), or aggregate review information—for example, the average rating for a local business or the total number of user reviews submitted.

Use the individual Review format for pages containing a single review. For pages containing a collection of reviews, use the Review-aggregate format. If your page contains both (for example, an editor's review plus a set of user reviews), we recommend picking one format. Use the individual Review format to mark up the editor's review OR you can use the Review-aggregate format to summarize the set of user reviews. If a page contains both types of markup, Google will use the Review-aggregate markup for display.

Note: There are many possible ways to indicate review ratings—for example, stars, percentages, and various rating scales. More information about how to convey review ratings.
