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.

You could also optimize this by using your Webmaster  tools and tell Google what your videos are all about. hope this helps. 
These 5 basic 
tips for video SEO are a good starting point for marketers looking to improve the “searchability” of their videos. 
1. Optimize with keywords.Just like any type of text-based content, video SEO involves optimizing  with target relevant keywords — both for search engines and for user  experience. Use keywords in:  File name Title Tags URL Link text Beyond that, include a paragraph of optimized text that provides a brief  
description of the video. Again, the benefits are twofold: You’ll improve the user experience and your search rankings. 
2. Distribute videos on video-sharing sites.In addition to posting videos on your own site, video-sharing sites are  effective tools for gaining visibility and additional links. Remember  these few points to maximize results:  Don’t forget that videos hosted 
on YouTube and other video-sharing sites should be optimized for keywords YouTube channel pages — and those of other video-sharing sites — should be optimized, as well Use a video distribution service like TubeMogul to deploy your videos to the top sharing sites 
3. Implement a linking strategy.Video is judged by the same linking standards as all other forms of  digital content. So building both internal and external links is crucial  for video SEO. Ideas for a linking strategy include:  Cross-linking to other videos Linking to videos from relevant web pages Linking to videos in 
blog postsTweeting the video Linking to videos from 
social media pages Bookmarking the video 
4. Encourage viewers to share your videos.First thing is first — if you want users to share your videos, you must  create content worth sharing. If your video isn’t interesting, relevant,  entertaining or informative, users aren’t likely to share it, let alone  view it. From there:  Allow and encourage users to comment on the video Make it easy for users to share your video on You Tube, Twitter,  Facebook and 
MySpaceOffer video content in multiple formats so users can choose the one that best suited to their platform and

5. Re-purpose your videos.As with text content, the more optimized video, the better. Get creative in order to re-purpose videos across the web:  Embed videos in blog posts Break up long videos and create multiple shorter ones Use transcriptions of videos to create blog posts or content for web  pages Take screen shots from videos and post them to Flickr and other  image-sharing sites Turn offline content, such as training videos or videos of a conference  keynote speech, into optimized digital assets for your website
