Google announced that it has launched rich snippets for music. This allows webmasters to mark up pages using the music markup to allow search results to display song info in the snippet.
The feature is already being utilized by MySpace, Rhapsody and ReverbNation. Search results would look something like this:
“As with other rich snippet formats, implementing the markup does not guarantee that your site will be displayed with the UI shown above on a given search; a variety of factors affect whether a particular rich snippet type will appear in our search results. However, having correct markup is a prerequisite for music rich snippets to ever be displayed,” says Associate Product Manager Gideon Wald.
Schema.org offers a set of guidelines for MusicRecording Markup:
Schema.org was announced by Google, Bing and Yahoo earlier this year as an initiative to support a common set of schemas for structured data markup.
“For now, music rich snippets will display song information when users search for artists, album names or song names,” says Wald. “We’ll continue working both on expanding our existing rich snippets formats and on creating new ones, so keep watching for updates about new types of content that you can surface for users right in your site’s snippets.”
