Did you know that YouTube is currently the 2nd largest search engine behind Google, with more than 3.5 billion queries a month. What that means is that there are more search queries on YouTube than on Yahoo! YouTube and other video sites can be a great vehicle to reach audiences who might not find you otherwise. Plus, you can create a branded YouTube channel and host your videos without incurring any costs.
This is of course not the only benefit of utilizing YouTube. The use of video can greatly affect your SEO ranking for several reasons. Search engines now display more and more videos in their results and weigh them more heavily. This gives you a great opportunity to increase your relevance in search results, and potentially achieve first page ranking of Google. In fact a video is 50 times more likely than plain text to appear at the top of search rankings.
