I've just found out that one of my video that I uploaded in youtube have PR3. I know that youtube is a no-follow link. But can you guys suggest on what to do on this video to make it valuable for me?
Youtube is only good for traffic. You get one dofollow link on your profile page, that's it as far as SEO is concerned. So if anything, you want your profile page to be PR3. But you can still annotate the video with a link to your site, in the hope that people will click on it.
that's right.. you can edit your profile on youtube and create a link on it.. just don't abuse it.. still relevancy make a difference..
Ordinary people don't know or care about PR, better if you find things how people would visit your site through youtube videos..
