"My gut reaction is that something bigger happened here than just a Panda data refresh, but I honestly can’t prove that."
From SEOMoz: "On June 5th of 2012, at around 9:00am Central Daylight Time, I spotted what appeared to be a major Google algorithm update in the wild.
Unfortunately, I was alone… and the photos all turned out blurry… ok, and I had had a few beers.
Still, that doesn’t mean it didn’t happen. This is the true story of an update that I honestly believe we missed, and why we’re just not as good at spotting them as we like to think."
Very interesting. 7/10
