If you want to add video information to a Sitemap or mRSS feed you must specify the location of the video. This means you must include one of two tags, either the
video:content_loc. In the case of an mRSS feed, these equivalent tags are
media:content, respectively. We need this information to verify that there is actually a live video on your landing page and to extract metadata and signals from the video bytes for ranking. If one of these tags is not included we will not be able to verify the video and your Sitemap/mRSS feed will not be crawled. To reduce confusion, here is some more detail about these elements.
Video Locations Defined
Player Location/URL: the player (for example, .swf) URL with corresponding arguments that load and play the actual video.
Content Location/URL: the actual raw video bytes (for example, .flv, .avi) containing the video content.
One of either the player
video:content_loclocation is required. However, we strongly suggest you provide both, as they each serve distinct purposes: player location is primarily used to help verify that a video exists on the page, and content location helps us extract more signals and metadata to accurately rank your videos.
URL extensions at a glance:
Sitemap: mRSS: Contents:
The playpage URL
The SWF URL
The FLV or other raw video URL
NOTE: All URLs should be unique (every URL in your entire Video Sitemap and mRSS feed should be unique)
If you would like to better ensure that only Googlebot accesses your content, you can perform a reverse DNS lookup.
