Including structured data markup in web content helps Google algorithms better index and understand the content. Some data can also be used to create and display Rich Snippets within the search results. For example, the Rich Snippet at the right shows search results for a movie, including review stars, an aggregate rating value, and vote count — very useful to anyone searching for information about this movie.
To make your pages eligible for Rich Snippets in search results, add structured data of the appropriate type to your content. Make sure to comply with any policies that each type has regarding Rich Snippet display. Google supports Rich Snippets for the following data types:
- Product -- Information about a product, including price, availability, and review ratings.
