I added Youtube...and hired tubeplays.com
two videos about my carbon copy business and asked those guys to get me rating.
I bought , comments, ranking, 100K channel views, for little money , I might add.
It worked for me. Google found me fast and I found myself on the second position of my main Keyword page in 2 weeks. I got around 130 unique hits per day and in two weeks 17 affiliates
I'm not saying it does not sound stupid but for me whatever gives results ...works.
I guess it would work for any business.
