There is no doubt Google has a human touch, we reported they may have close to 10,000 evaluators and their guidelines were leaked – so this is no secret anymore.

The question is, how do you know if one of these evaluators are on your site, sniffing things out?

A WebmasterWorld thread suspects that the Google evaluators come from cart.corp.google.com. In fact, WebmasterWorld administrator said he always sees the “first parameter” string along with a “?cmd=review.” To him, this implies it is an evaluator.

Should you worry if you see this in your log files? Depends, are you doing anything shady or borderline?
