Same thing happening here. Drops across the board of about 3-7 positions. About 60% of our traffic gone because of it.
Thanks for the insight. Very useful! I agree, once we were able to step back and look at stuff (with the help of someone who doesn't stare at the site all day)....all of a sudden the boilerplate content and duped content started to stick out like a sore thumb. What we thought was helpful to the customer (which definitely is) Google wasn't a fan of across thousands of pages.
I'm curious with the new Panda, where it is rolled out weekly or so, what that will do to recovery time. We saw our drop of 60% over a 2 month period of time vs. one big drop. I wonder if the recovery will be similar, slowly regaining 7-10% of your referrals as they re run the Panda weekly.
