before, the ads used to be related to the page that you were on. so for example, if you were on a page about ebay sniping software, the google ads on that page were also about auctions and softwares... but now, the ads are more related to the things you have been searching for recently, and not necessary related to the page's topic. so for example, lets say you have been searching for red wine in google...and you go to a page about ebay sniping software, the ads on that page are going to be about red wine and not about auctions. so goog is saving your searches and displaying ads according to what you have been searching for recently, NOT what the page's topic is about. this is something i noticed recently, i am not sure how long they have been doing this.
