Google Panda 4.1 Rolls Out
Google has rolled out a new version of the Panda algorithm, and it’s believed to affect 3-5% of websites. That may sound like a small number, but as Google algorithm changes go, it’s a pretty big one.
Google’s Pierre Far announced the update on his Google+ page two weeks ago. He explained that it’s not a simple update because it actually adds a few more signals to help Panda identify low quality websites better. Assuming your website is not a low quality site, this should work in your favor. In fact, he says this update results in a”greater diversity of high-quality small- and medium-sized sites ranking higher”.
There’s a nice Panda overview and guide to Panda 4.1 over at The Huffington Post.
The rollout is a slow one, not hitting all Google data centers at the same time. It wasn’t expected to continue into this week, but according to Moz it was still rolling out as of three days ago. They say “fluctuations and ranking changes you are seeing are likely related to that.”
There are a series of questions you can ask and answer about any given web page that should give you an idea of whether Panda will like it (improve its rankings) or not (potentially drop its rankings). The Moz blog of two days ago goes through that for some representative sites that were helped by Panda 4.1 and some that were hurt. There are also links there to some places where you can get a page evaluated … but the easiest one (PandaRisk) costs about $100 to evaluate a handful of pages for you.
