My websites haven't been ranking in the top 100 for my keywords yet. I sent web 2.0s with high pr posts to the web 2.0s. I also sent a few pbn posts to each money site. The sites are still no where on the top 100 though. Why is this? What can I be doing in the meantime while I'm waiting for these sites to rank? Build more links? Or wait until I see an effect from the links I just built?
