When I was at the Search Insider Summit a few weeks ago, there was a panel on video search optimization. One of the panel participants was Christy Tanner from TV Guide. It was interesting to learn about how most video search works and that there is a distinction between video hosted search and video search. The latter uses thumbnails and meta data for videos and points to wherever the actual videos are hosted.
TV Guide now offers an online video guide that distinguishes itself from other online video search by focusing on professionally produced video content such as, movie trailers, TV shows, news clips, previews and programs across all genres and networks. Without consumer generated content, the TV Guide video search site makes it easier to find popular TV programming.
