One of my big money makers got penalized (not banned) recently. We had over 500 terms on the first page and many that were high level keywords driving huge amounts of traffic. Then one night at around 11 pm I noticed the traffic suddenly dropped off to nearly nothing. I checked my ranking reports and there it was...we dropped to 4-5-6-7-8-9-10th pages with all terms. A loss of over $100K per month in revenue.
So after a couple of days of hanging out with Jack Daniels and feeling sorry for myself I figured it was time to get back to work and get her fixed. I figured we were not banned, just penalized, so therefore I would comb the site and try to fix anything that did not follow Google's guidelines.
Now, I have many sites that I own that have had zero issues so it made it a bit easier to narrow down the issues. That is unless one of our competitors reported us, which would not surprise me because it is a cut throat niche.
So long story short we removed any potentially incriminating offenders and filed a reconsideration. After waiting 2 weeks we got a response back from Google saying that our site was still in violation of their quality guidelines, but they did say that we need to remove or fix duplicate pages on our site and then file another reconsideration. I said to myself "wait did I just read that right"? Google actually told me in a round about way what we did wrong, which is new for them.
In conclusion, we removed over 500+ geo pages on our site that were very similar to each other with minimal changes on them such as the title tag, description and a few minor changes in the content. I also had a article syndication script on the site which was taken off. I submitted another reconsideration to Google and we are praying that this time works.
So my question is, has anyone here been penalized in Google and gotten their site back to were it was after reconsideration?
