@ohno, yes, I did a ton of changes. But now I am left scratching my head a little bit. I am now not sure if whether anything I did helped "fix" my site or whether Google was just allowing the algo to "run its course". From what I'm seeing, the first slap seemed like a small US set was hit. This next round encompassed a wider range of sites. I felt singled out in my niche but now, a lot of big players in my niche are down in a big way.
It makes me think that this algo is made to "reboot" the web. Then it learns over time. In the meantime, I was doing what I could to make fixes and I did a full site audit and noticed a lot of "holes". I acted on what I could and I am actually not done yet. So now, I am not quite sure if my actions had any direct results as my recovery was in a gradual "wave" form. A big hit, then it went much lower then it got better over the next couple of weeks, with 10% improvements each week. Now it's back down at the lowest levels.
My guess is that there was some data collection going on the first time based on a subset of sites and phrases (in the US). Now it's loose everywhere and their algo will be reworking ranks based on stats, etc.
