I know a little bit about seo and I read a lot of forums on how I should go about getting ranked high on a specific keyword. I've already done a 21 Web 2.0 Properties, 3-tier link-pyramid. However, it wasn't enough. The keyword I used started as low competition but now it has reached medium so now I'm kinda need some more advice. If possible, I need llike a list of high pg rank sites to post to so I can get more back links. I believe backlinks are the most important. thanks.
