I have a YouTube Channel that I created about 8 months ago. I have over 30 videos I created that are 100% unique. I have not done any SEO or anything to increase my PR on my main channel page. With that being said I now have a PR5 channel page and 15+ individual video pages of mine have a PR1-2. With all the above being said... How can I benefit from a PR5 YT Channel page?
That's why the traffic will matter. Even if you have a high PR it won't matter unless you have traffic. People will pay for a nofollow link if the traffic is targeted.
Other way is link to your website, if you have one. Many youtube user have a selling website, so youtube visitor will go to your site directly.
