Its insane how we went from a gradually increasing ranking ... page 72 ... to page 21 ... to page 7... to page 2 .... to page 1..... over a period of 2 years and then I buy an AdWords account and mysteriously .... within 3 weeks, we drop from page 1 to page 36 on all our key words?
Ive owned a successful site for over 7 years and i know exactly how to get to the top of Google. I know for a fact nothing has changed on my site nor our link popularity.
The only thing I did differently this time was sponsor some ads, and ever since we did that, our free rankings have dropped and have not recovered.
I have many clean sites, several of them dropped out 6 weeks ago, some 4 weeks ago and some dropped out yesterday, seems to be big changed going on, not good ones though.
I also had a new adwords campaign 6 weeks ago which seems to cause some sites to go, but when it happened, many people moaned in this forum too so I assume it was not related, but who knows.
Still, if anyone using the internet wants to view the unique content on my site that's no longer in the google index, there are hundreds of scraper sites out for my keywords still showing it!
At this point I am thoroughly convinced that if you have a new site, and you set up an AdWords account, your free rankings drop dramatically.
It could be coincidence.
I'm firmly in the coincidence camp myself - although I do know that a Googler chiming in (yet again) to say "No connection at all between search results and Adwords, folks!" will not necessarily convince everyone. ;)

Did you lose your DMOZ listing? I've noticed that has a HUGE affect.
