I saw the official Panda 22 anouncement on SERoundtable. (Had been checking for days.)
As posted previously here, I benefited. On the order of 40%, which puts me at half the traffic I had before hit by Panda 2.0.
As others have discussed here on WebmasterWorld, I think Panda measures searcher satisfaction with your site via
metrics like "long clicks" from the SERP's, and few bounce backs to the SERP's to click the next listing.
I think you beat Panda by making your website better meet your visitor's needs.
Anyway, here's what I have have to say. For the last 4 months or so I have basically been making one type
of change on my site. I have about 20 related topics. I have simply been providing better navigation between
the pages within each topic. I ended up using page-top tabs navigation.
When improved navigation was implemented in a section, its bounce rate dropped (instantly) about 20%.
Pages-per-visit and time-on-site improved too. To me, that meant my website was better meeting the
needs of my visitors.
Adding this navigation has been difficult for me and has taken a lot of time (4 months so far). Of course, I started with my most-trafficed topics. (I wanted the biggest bang for my efforts up front, these first topics accounted for probably 75% of my traffic.)
Slowly I continued on with each successive topic.
Right now I've completed this task on 90% of my total pages.
Here's my point. I started this task 4 months ago, and created an immediate improvement in user stats for the VAST MAJORITY of my TRAFFIC (visitors), yet 4 or 5 Panda updates passed me by without effect.
But now that I've completed work (and improved user metrics) on the VAST MAJORITY of my TOTAL PAGES (about 90% of pages have been improved), finally I get a partial Panda release.
To me (as mentioned in my previous post here), this explains why I benefited from Panda 1.0 and got nailed by Panda 2.0 (the first Panda update to evaluate the "long tail" more closely).
When Panda 1.0 evaluated just my core, high-traffic pages (money-keyword pages) I evidently had good enough user stats (see my previous post in this thread).
When my long-tail pages were included in the Panda 2.0 evaluation I got Pandalized. I had too many total website pages that demonstrated poor user experience.
Just my opinion. Hope it can help someone.
