Do you have any sites hit by Panda on October 14th or earlier?
Here's a quick case study of my site in a competitive niche that got hit hard by Google Panda 2.6 on October 14, 2011.
I made some changes and on November 3rd, it started recovering. Quickly, I was back at 100% Google love once again.
Here's the case study:

I'm new to posting on a blog for my peers/friends. So please post your feedback so I can improve
Nice one. thanks for the post.
Impressive recovery:

Critical point you made is this:
Well done Mr Panda Slayer!
You will see that pattern on most "good" sites affected by Panda. 90% of my sites got all their traffic back without me doing anything different from what I did pre-Panda. The only sites that where affected permanently where those who had manual reviews - article directories where hit hardest.
My main money site looks like yours traffic graph on Oct 14th. I still haven't seen a recovery and I have thrown some very high quality links at the site. I am thinking I need to get some good content posted and indexed and hopefully lift the panda penalty.
Thanks for the case study.
Nice recovery, not for me either, I had a moneysite going from about 200 unique visits/day to now around 10/day on Oct 14.
I had some duplicate titles (something you always need to check!) on the blog, but didn´t recover despite of correcting that and resubmitting the sites.
I have no clue what more to do, thanks to my kungfu seo it survived the earlier attacks by the big Panda, but this was a sneaky panda move while I was sleeping :-)
This is a "real" site with good quality articles and affiliate links... And a blog attached to it, which gets 2 new relevant short posts a day (real stuff).
Well, that´s life, another reason why I joined this foruma a few days ago. Always knew I had to do more paid traffic, but free seo traffic is nice when it works...
I wasn't affected by the Panda but my site got hit on the 18th of November... it went from $250+/day to $20-$50/day (#3 to #19 overnight). I suspected a few things that caused this drop and I'll do a case study on that as well. Nice share btw, learned a few things that I will implement in my case study.
Anyway to cloak panda so it doesn't 'see' affiliate links on your site, just links to other authority sites? That would be cool to know!
