Last month, Google launched a refresh of the Panda update. The company tweeted on March 23:

Today, the company finally put out its monthly list of algorithm changes for the month of March. While there’s not a ton of new Panda information, that update is referenced with just a bit more explanation than what was available before.

Here’s what the relevant Panda part of the post says:

High-quality sites algorithm data update and freshness improvements. [launch codename “mm”, project codename “Panda”] Like many of the changes we make, aspects of our high-quality sites algorithm depend on processing that’s done offline and pushed on a periodic cycle. In the past month, we’ve pushed updated data for “Panda,” as we mentioned in a recent tweet. We’ve also made improvements to keep our database fresher overall.

There’s that emphasis on freshness again.

There’s actually another entry on the list referencing site quality, that’s worth noting. This change goes by codename “Curlup”:

Improvements to processing for detection of site quality. [launch codename “Curlup”] We’ve made some improvements to a longstanding system we have to detect site quality. This improvement allows us to get greater confidence in our classifications.

In Google’s February list, the company mentioned another update to Panda, which made it more sensitive.
