Hi,
Thanks for this important post. We think Video
SEO is the most important skill to learn in 2009.
Aside from concentrating on the 'metadata' there are things you need to do to the film itself. Examples are:
1. Name the movie after your main keywords
2. Embed your URL throughout the movie - Many video serving hubs remove or truncate your metadata when copying it.
3. For You Tube - Ensure that the frame at the midway point of the video contains your selling message or some thing of interest, this is where Youtube takes the default picture from.
4. Sign up to a video syndication and distribution service.
