Using a tracking cookie, Google stores info based on your searches to better target ads at your ass. Aaaaaand now you can see what demographic (I'm a cat!) Google thinks you belong to by visiting their ads preferences site HERE. You can also opt out of the tracking cookie's use on the same page. Me? I ate mine. This is a screenshot of my actual info though, so as you can see Google thinks I'm an ageless, sexless (admittedly true *sad face*) fan of coloring games. "And not a deviant porn freak?" Hey, I'm as shocked as you are.
