Does your google history really affect the ads you see on one independant website ?

if the website is serving google's adds, you're damn right they're targetted at you personally.

a week after i got back from vegas last year, hotel receipt hits my gmail, and every freaking ad was about vegas hotels.

We all know Gmail uses text clues to serve ads. The question was about the ads on an independent website?

Yeah, Google can track your intentions not only by search queries or your email(if you use Gmail that is), but also the sites you visit - if they run Adsense/Doubleclick ads.

i didn't mean gmail adds--i mean, every add, on every site that uses adsense, ever.
