After the Austin update my website rankings vanished from google serp's. Initially i panicked and started cutting down on keyword density, adding new content etc, but after a month or two i didn't see any improvements, so i decided to stop trying to optimise my website in order to rank in google.
Luckily for me Yahoo started using their index and my site started ranking for several competitive keywords/ keyword phrases.
I think there was a mini-update a few weeks back which resulted in my website rankings returning to the google serp's and doing better than ever before(several top 10 rankings).
Has any one else that was booted during Florida or Austin seen their sites return and improve in rankings.
All I did was concentrate on all the usual things such as title and anchor text. I also added new content and played around with the page titles. To be fair there was a suggestion at the time that my problem may have been partly due to the fact that I had linked to a bad neighbourhood.
While my site was gone I spent many hours adding new content, tweaking and improving it. Since it came back in May I have held the number one position for the main KW. Long may it continue!
