Question: What is it and how should I implement it?
Answer: Video SEO is the process of making videos on your site accessible and readable by the search engine spiders. This has become more important due to universal search in Google which display videos on their search results. Due to the limitation of text for the search engine spiders to figure out what your video is about they have to rely on the title and alt attributes that are in your video as well as citations from external sites. You could also optimize this by using your Webmaster tools and tell Google what your videos are all about. hope this helps.
