There is much you can do right with YouTube but there is also a lot of things you can do wrong! For instance all of my affiliate videos are on the same channel, if Google decided i violated their tos I would have to start all over but Google see the value I bring. I would suggest using different channels for different niches rather than having 1 channel or 1,000 channels.

Google PageRank (Google PR) is one of the methods Google uses to determine a page's relevance or importance. Important pages receive a higher PageRank and are more likely to appear at the top of the search results. Google PageRank (PR) is a measure from 0 - 10. Google Pagerank is based on backlinks. The more quality backlinks the higher Google Pagerank. Improving your Google page rank (building QUALITY backlinks ) is very important if you want to improve your search engine rankings.

Well you always write about the keyword “SEO” while giving YouTube examples. How can it help to YouTubers who don’t have any blogs or website (in step 3 – description part)? You could have given examples of YouTubers who are in entertainment industry as well because the people who visit your site are not necessarily webmasters. They could be anyone.
I was wondering if you are still following the replies here..and if you question: I used to be able to land a video on page one of GOOGLE for just about anything as long as the search count was typically under 500,000. It seems now, it is more difficult even to land on the first page for something like this..(and please go look at the examples and provide your input if you are still monitoring this page)
Hi Brian, Thanks for sharing your insights on youtube SEO. I recently had my video go viral (it has gotten almost 145,000 views on YouTube and Twitter within a week). The tipping point seemed to be that it was tweeted out by someone as “The Worst Ad on YouTube.” Strangely this person does not have that many followers but it seemed to pick up a tremendous amount of views very quickly. I was running Adwords and Facebook campaigns, but at a pretty low level. Any insights?
This content will help you boost your rankings in two primary ways. First, more content means more keywords, and therefore more opportunities for Google to return your site in the search results. Second, the more content you have, the more links you generally accumulate. Plus, having lots of content is great for getting visitors to stay on your site longer. Win-win!
