As keywords are essentially the backbone of on-page SEO, you need to pay a lot of attention to them. There is no reason not to include them in your URLs. The inclusion has its benefits. When you assimilate the targeted keyword into the URL, you are ensuring that Google’s has another reason and way to consider your article as more relevant for a particular phrase.
Just for the record I make a substantial living from YouTube marketing and I also run my own SEO firm with over 250 clients with Google Front Page Rankings. Now I use Fiverr for my YouTube rankings and I agree with Brian but would also like to add a little more value. After you do what Brian suggest visit Fiver and find someone that dripfeeds views for 20 days. 100 views a day for 20 consecutive days works wonders with the right backlink profiles. I’ve ranked for several medium competition keywords without any backlinks. Google will rank your video with social signals from just YouTube. Here is my formula 100 likes, 50 comments, 10% dislikes, 100 subscribers driven from the video, 50 video embeds and about 250 Facebook shares and likes, then build backlinks. There is a link to my Youtube channel feel free to Google search any of my keywords.
I was wondering if you are still following the replies here..and if you are..my 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)
