Sitemap Extensions

The sitemaps generated by the Sitemap plug-in can, if required, contain extension elements. The extension elements allow you specify additional information about certain types of content that will be used by some specialized search engines. The extension elements belong to different namespaces from the standard sitemap.org elements and will therefore be ignored by any search engines that do not recognise them.

The sitemap extensions that are currently supported are defined and used by Google:

Google News sitemaps

This extension lets you identify content that you want to be submitted to Google News. See Google News Sitemaps for an example of a sitemap containing these extensions.

Google Video sitemaps

This extension lets you identify content that you want to be submitted to Google Video. See Google Video Sitemaps for an example of a sitemap containing these extensions.

You can activate these extensions for some content types and not for others (see Editing the content-type Resource for details). You would, for example, only activate the Google Video extensions for content types that contain video clips.
