I dont think you need to wait till the next Panda/Penguin update to see this happen. Its already happening but slowly. Eventually they will turn it on full power and thats when our sites will take those huge hits. Iv noticed today, my traffic has dropped by more than half. Usually, by this time of the day (1pm), i have about 200 uniques visitors but so far today its just 80. Thats a huge drop in traffic. This means that i wont be seeing 400 users visiting my site by the end of today. Checking my keywords iv noticed that most of them have dropped at least 5 or more positions even though they are still on page 1. Iv also seen another one of my sites go from page 2 to page 3 over the past week, no matter how much backlinking i do. It seems the more i do the worst it gets and not doing any backlining is as bad as doing any? WTF. I fucken hate Google. Those MFERS are ranking linkedin profiles for some of my keywords in the #2 and #3 positions for some of my keywords? Are you kidding me with this? Linkedin profiles?
