Over the last 14 days I built about 40 tumblrs with pa30+ TF/CF 10+ to one of the blog posts on my money site. Yesterday I checked all of them and some lost its power so I removed them. Problem is that when I started I was ranking on 30. place for the main keyword and now I am around 50th place. I did the diversity of anchors, naked url's, branded, etc.. Do you think ranking dropped because I had some tumblrs which lost power? I removed them yesterday how fast do you think I should see the increase? I used posts backlinks and profile description links as well. What do you think it is the problem?
