Yes/No, which is a wishy washy answer. I have looked at thirty DC’s and seen the results completely reverse themselves in 12 hours. All sorts of sites moving up and down. It seems like they’re doing an update at the same time they’re testing Caffeine. I would agree with RB it seems big. Seems like Google is picking up things from Yahoo and Bing. I judge it by the bottom line though and this has been the worst month in ten years. Either people are very, very, broke or Google is screwing around way to much. Whiteknight is right in that Google has been testing far longer than most people think. I was exploiting it in the early days.
