Youtube is such a good venue for website promotion. When your video gets popular, expect more hits going to your site.
I heard, that to advance through youtube, it is necessary to insert the link into video, but I cannot understand as it to do. Can I something not so have understood?
Youtube is a great source for high PR backlinks. In fact, my service not only submits your article to youtube (with narration), but 20 other video sites. These are all great for back-linking and traffic in general. (don't forget taking the audio and submitting it to podcast sites) You don't need to promote the video, in most cases it is better for a backlink.
