This has happened to myself and a few others I know. One day, I'm the # 2 and 3 results for a specific keyword, then the next I'm not even on the top 10, top 20, etc.. no idea which page I ended up on. On the 26th I had a record high of 26k hits. Today I'm down to roughly 4k, and nowhere to be seen on google for that keyword. What are some things that could get my site(s) booted? Once booted from the top 10, how can I get them back? It seems like they've become blacklisted... one was gone once, then came back to the top 10 and I didn't change anything. Really fucks with my earnings.
