I can't be the only one to have noticed lately the large and ever increasing number of threads about the Google dance, deindexing etc over the last week. I believe it was about a week ago my whole network of 80ish sites dropped. The common thread was almost all of them were built upon profile backlinks. They had solid rankings for over a years time and I had done nothing new to them in months. They suddenly dropped off front page for their keywords. I'd suggest building web 2.0 links (or like mojpoj posted videos, articles etc) pointing to your site and blasting those. Many would argue this is better practice anyways. Okay this is pretty much common sense this thread lost a lot of its intent when I changed this post. Edited the thread because I hadn't considered a crucial detail; however, I'm still up in the air about what happened to my network. Leaning towards GooglesMostWanted's opinion that maybe the links were slightly devalued and since this is the base of the backlink campaign these sites had that could be the reason. I bought the sites and have more than doubled my 8k investment on them so regardless it worked out well, but obviously I should work on them a bit more. The basic idea was that a massive number of profile backlinks pointing to sites seems to be causing a drop in rankings based on recent observations from the time when all of mine went down at once about a week ago until now. Could very well be user error on their part and there's something I'm missing for my recent drops. For sake of discussion, do you guys think Google has done anything to profile links since that panda update, or possibly since then?
