The answer to this question USED to be "no," but I've heard that google is starting to crawl youtube comments (or it's a feature in labs or the like), which might change things. Can having strong video content actually improve your SEO?
It seems like it depends on where and how it's hosted. I don't see how getting even a million youtube hits helps you if no one visits your site. The youtube video has to have some kind of funnel to your homepage, and even then -- does that count for any more than just a single backlink in google, yahoo, et al
Any thoughts or inside info on this?
