Google Webmaster Central has released a few Youtube clips describing the best methods for indexing video content, to supplement their Webmaster Tools dialogue. Google states that when video content is marked up in the body of the page, search engines and other sites can recognize it, and may use it to improve the display of video content on a page or in search results. Marking up content provides information about videos that allows Google and other sites to index them. Along with a description of common video indexing mistakes webmasters make, Google also added tips on video indexing markup, as well as a clip on video platform restrictions.
Google also added a clip about schema.org, a set of standards that Google, Microsoft and Yahoo have jointly initiated.
Search engines are utilizing on-page markup in a number of ways. For example, Google uses it to create rich snippets in search results. Not every type of information in schema.org will be surfaced in search results, but over time, one can expect that more data will be used in more ways. Google currently supports rich snippets for people, events, reviews, products, recipes, and breadcrumb navigation, and the new schema.org markup can be used for these types.
