Review snippet

Does your site provide reviews from critics? Use critic review structured data.
Does your site provide reviews about other employers? Use Employer Aggregate Rating structured data.
Does your site review claims made by others? Use Fact check structured data.

A review snippet 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 ratings 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 appear in Google Search results may appear under a search result or in Google Knowledge Cards. You can supply ratings for the following content types:

• Local businesses
• Movies
• Books
• Music
• Products

Examples

There are several ways you can add review structured data to a page:

• Add a simple review.
• Embed a review into another schema.org type using its review property.
• Add ratings to your reviews.
• Add aggregate ratings. You can omit the rating for an individual review if your marked-up content contains both an author and a review date. For aggregate reviews, you must supply the average rating for the rich snippet to display.

Guidelines

Your content must follow these guidelines to be eligible to appear as a rich result.

Warning: If your site violates one or more of these guidelines, then Google may take manual action against it. Once you have remedied the problem, you can submit your site for reconsideration.

• Technical guidelines
• Content guidelines
• Webmaster guidelines
• General structured data guidelines

Technical guidelines

• Make sure to mark up an aggregate evaluation of an item by many people with schema.org/AggregateRating. Google may display aggregate ratings as rich snippets or, for certain types of items, answers in search results.
• Refer clearly to a specific product or service by nesting the review within the markup of another schema.org type, such as schema.org/Book or schema.org/LocalBusiness, or by using a schema.org type as a value for the itemReviewed property.
• Make sure the reviews and ratings you mark up are readily available to users from the marked-up page. It should be immediately obvious to users that the page has review content.
• Provide review information about a specific item, not about a category or a list of items.

  Recommended: Hesperia Madrid Hotel

  Not recommended: Top 10 hotels in Madrid

• If the critic review is for a local business, you must follow these additional guidelines:
  • Ratings must be sourced directly from users.
  • Don't rely on human editors to create, curate, or compile ratings information for local businesses; instead, use critic review structured data.
  • Sites must collect ratings information directly from users and not from other sites.

Structured data type definitions

You must include the required properties for your structured data to display in search results. You can also include the recommended properties to add more information to your structured data, which could provide a better user experience.

Review

The full definition of Review is available at schema.org/Review.

Required properties
author	Person or Organization The author of the review. The reviewer’s name must be a valid name. For example, "50% off until Saturday" is not a valid name for a reviewer.
itemReviewed	Thing The item that is being reviewed. This needs to be a valid schema.org type. However, if the review is embedded into another schema.org type using the review property, you can omit the itemReviewed property.
reviewRating.bestRating	Number The highest value allowed in this rating system. The bestRating property is only required if the rating system is not on a 5-point scale. If bestRating is omitted, 5 is assumed.
reviewRating.worstRating	Number The lowest value allowed in this rating system. The worstRating property is only required if the rating system is not on a 5-point scale. If worstRating is omitted, 1 is assumed.

Recommended properties
datePublished	Date The date that the review was published, in ISO 8601 date format.
publisher	Organization The publisher of the review.

ratingCount	Number The total number of ratings for the item on your site. At least one of ratingCount or reviewCount is required.
reviewCount	Number Specifies the number of people who provided a review with or without an accompanying rating. At least one of ratingCount or reviewCount is required.
