I had an authority site i was developing and it just got slapped hard. It was ranking on the first page for a bunch of keywords and one day, BAM rankings for ALL keywords dropped and now I'm not ranked for most of them and only a few on page 7 or 8. I'm totally pissed... wtf? I don't have webmasters installed so I don't know if it was unnatural links or whatever. I mostly used UAW/Onlywire and some profile/bookmarking services to rank. What can I do to regain my rankings? I'm sad... spent so much time and money on it. DAMN.
