As usual, webmasters are speculating that there may have been a Panda update refresh. Once again, Barry Schwartz at Search Engine Roundtable is pointing to a WebmasterWorld thread where such discussion is taking place.
Various people are reporting that they’re seeing significant changes, speculating that there was an update on May 30. We’ve reached out to Google for confirmation one way or the other. Sometimes they’ll confirm, others they won’t. Sometimes they’ll tweet about the refreshes. Other times they won’t.
Right after Google told us last week there hadn’t been a Penguin update since the first one, Matt Cutts tweeted this:

@mattcutts Minor weather report: We pushed 1st Penguin algo data refresh an hour ago. Affects <0.1% of English searches. Context: http://t.co/ztJiMGMi
So I guess you never can know for sure.
One thing that I’m pretty sure of, however, is that Google will be releasing its monthly list of algorithm changes in the near future. It’s the last day of May, which means it’s just about time to see what all Google has done over the past month. These are always full of interesting nuggets of information.
In other Panda news, Google is including some of its guidance for webmasters regarding the quality of content in its recently launched Webmaster Academy.
Apparently Google’s Amit Singhal has been eavesdropping on people talking about it in coffee shops as well:

@theamitsinghal Overheard next table at Starbucks, “With Google Panda and Penguin our tricks don’t work.” Glad they didn’t recognize me.
