In our effort to help users search all the world's public videos, the Google Video team joined the Sitemaps folks to introduce Video Sitemaps-an extension of the Sitemap Protocol that helps make your videos more searchable via Google Video Search. By submitting this video-specific Sitemap in addition to your standard Sitemap, you can specify all the video files on your site, along with relevant metadata.
You can create Mobile Sitemaps using the Sitemap protocol. You can do this manually or you can use our Sitemap Generator. If you plan to use a third-party tool, you should check to see that it can create Mobile Sitemaps.
