Last month, Google’s Matt Cutts made some comments at the Search Engine Strategies conference, reportedly indicating that the next Penguin update would be “jarring”. Since then, webmasters have been waiting for the big day when Google drops the hammer.

Last week, there were some rumblings in the forums, and further in our own comment threads, about a possible update, but Google has been silent on the matter.

Barry Schwartz at Search Engine Roundtable is pointing to more rumblings today, saying that he suspects a Penguin refresh.

The rumblings don’t seem to be heavy enough to suggest anything too “jarring,” so he may be right on the data refresh. Or it could simply be something else entirely. Google makes changes every day.

Sometimes Google will actually announce an update or a data refresh. Sometimes they’ll do so in a simple tweet, however we have yet to see a tweet. Google’s big list of changes for the month of August is about due out, although last time, we had to wait two months for two months worth of changes, so who knows when that will actually come? They could simply inform us of any Penguin-related changes in that.

The last Penguin refresh, which Cutts tweeted about, came in late May.
