Google has confirmed that the latest iteration of its Panda algorithm update is live. Based on our tracking of the algorithm changes, this is Panda Update 2.5.
Google declined to share any specifics about what types of sites, pages or content this update targeted, instead only sharing the company’s default statement:
We’re continuing to iterate on our Panda algorithm as part of our commitment to returning high-quality sites to Google users. This most recent update is one of the roughly 500 changes we make to our ranking algorithms each year.
WebProNews reported this morning that the update rolled out on Wednesday, September 28. We’ve heard from other sources that it rolled out on Tuesday. It’s the longest gap between Panda updates since April.

Did you mean version 2.5? I believe 2.4 rolled out awhile ago: http://www.seomoz.org/blog/panda-24-and-analytics-session-update-rolled-out-simultaneously
Very interesting: several of my sites which were hit by the first Panda haven’t recovered yet. Only one recovered (at the end of July), but that has now lost 30% of organic the last 2 days. Only this one was hit in this latest panda, while none of the others were, even though they are similar sites.
Thanks Google; I am getting more traffic, now and I didn’t do a thing- I don’t even have a blog.
Do you know if this update is global or only affects english/US sites? I own several spanish sites and I’ve seen no changes this week in traffic.
Yup, my site recovered most of its prior traffic when Panda 2.3 rolled out in July. Then on Wednesday night I watched in real-time as my hourly traffic started to dip…
I was pretty sure something was happening and that it wasn’t due to anything I’d done. I suppose it’s nice to have confirmation, but I’d rather have my traffic back.

We updated the story as noted but not the URL. We’ll fix that. And no, that’s just someone ripping off our content. Sadly, it happens to everyone. We’ll send them a notice.
my blog just recovered from the last update and this mornig they hit me again. I lost 70 procent of traffic, just like last time. They hit all over the world. I`m from Romania. It`s gonna happen every time they will roll the update? (excuse my english)
@Chas
Can you give us the url of your site ?
What is the main point of Panda updates flux and 2.5? How could Google realize?
