Google Updates “Panda” Filter, Impacts 7.5% Of Search Results

Yesterday, Google has made a significant change to their Panda filter, named Panda 4.0. This is the biggest update to the Panda algorithm in ages and may be the cause of some ranking changes you may be noticing in Google today and throughout the week.

Google’s head of search spam, Matt Cutts announced on Twitter that the update Panda filter began rolling out yesterday. Here is Matt’s tweet:


Google told us “Panda 4.0 affects different languages to different degrees.” Adding that “in English for example, the impact is ~7.5% of queries that are affected to a degree that a regular user might notice.”

That means this update is the largest Panda update since Panda 6 on Aug. 12, 2011, which impacted the international space by 6-9%. But this is indeed the largest update of Panda for English queries since Panda launched on February 24, 2011, where it had a 11.8% impact on queries.

Why such a large change? From talking to Google, it sounds like this update will be gentler for some sites, and lay the groundwork for future changes in that direction. So it seems like Google has made some major and fundamental changes to the Panda algorithm.

    Jared is to subway as Matt cutts is to google. He’s a great mascot but I am not convinced he does much hands on work behind the scenes considering all these updates favor google either which way. It’s a ping pong game they are playing and now seeing that eBay and are being sandbagged in the results shows that googles efforts of being number one in the world is coming closer and closer. You know I don’t think it’s a coincidence they just released google glass to the public and now are hiding major shopping and advertising sites. Just saying.
