Video Optimization Encoding The video file should be encoded with metadata including keywords, descriptions and titles. You can use window media cleaner to encode your video. The video file name should include the target keyword (use dashes between words) and be a recognized video file format. Google can crawl the following video file types: .mpg, .mpeg, .mp4, .mov, .wmv, .asf, .avi, .ra, .ram, .rm, .flv. All files must be accessible via HTTP. Metafiles that require a download of the source via streaming protocols are not supported.
Site architecture I recommend that video content is grouped together on the server in a subfolder or subdomain. This makes is easier to block indexing of multiple formats as well as to create video sitemaps. If you’re offering multiple formats for your audience, it is important to block search engine indexing of duplicate versions via your robots.txt.
Video length Given the attention span of the audience, most videos should not be longer than 3 minutes. If your video needs to be longer, break it up into smaller pieces and label it accordingly.
Watermarks Commercial content should include a «watermark» to indicate origin. This will help if your video goes viral, and is copied to multiple sites, because it will still carry your branding message and/or site information. The brand and/or URL should also be mentioned in the video content.
Players Please be aware that if your video is displayed on your site in a popup or embedded player it may not be indexed by the search engines. Check the site code to ensure there’s a clean link to the video file. If not, consider use of SWFObject. Sharing Elements: Video sharing sites and on-page tools will contribute to building both links and additional traffic. Adding sharing elements can help the video spread virally. This would include embed scripts that allow users to email or embed the video in a webpage or blog. Displaying the video’s full link makes it possible for a user to submit the video to social
Video Sitemaps What to include in the video sitemap A Video Sitemap should contain only URLs that refer to video content. Video content includes web pages which embed video, URLs to players for video, or the URLs of raw video content hosted on your site. Each video is uniquely identified by its content URL
