Google, Bing and Yahoo have announced an alliance of the website schema.org. The alliance provides a common foundation of support for a set of microdata types. Microdata is a type of structured mark up that can be used to provide meaning to content on web pages. Schmema.org provides a collection of schemas, like html tags. Webmasters can use these schemas to markup their pages in ways recognized by search providers. Search engines rely on this markup to improve the display of search results, which will help make it easier for people to find the right web pages.
Search engines can benefit from direct access to structured data. On-page markup enables search engines to understand the information on web pages and provide richer search results in order to make it easier for users to find relevant information on the internet. Google, Bing and Yahoo have all come together to provide a shared collection of schemas for webmasters to use.
