Earlier last week, Google pushed out an update to the Google Panda algorithm.
I didn’t see it before going offline for the holiday but Google confirmed the update based on a WebProNews story featuring DaniWeb getting hit again by the update.
In fact, Dani from DaniWeb posted in the Google Webmaster Help forums complaining:
However, we were hit again on Wednesday, September 28th, once again losing more than half of our traffic. I think this might even be a bigger hit than last time. I am still investigating whether or not this was another iteration of Panda that just went out or something different?
Wow, lost half their traffic again, after all that work to get back in!
SearchMetrics released their stats on who was hit the hardest by this update and Danny has a good summary of that at Search Engine Land.
Google said this update hit sometime on Tuesday and people started to take notice on Wednesday. Google confirmed it on Thursday.
Here is the update history:
Panda 2.5 on September 28th
Panda 2.4 in August
Panda 2.3 on around July 22nd.
Panda 2.2 on June 18th or so.
Panda 2.1 on May 9th or so.
Panda 2.0 on April 11th or so.
Panda 1.0 on February 24th
