No... ads are directed towards the collected tendencies of the viewer's ISP. This is the internet censoring you from poop you don't care about. [Or poop that you don't get the chance to decide whether you care about it or not [;)] ]

It serves ads based on what you have searched for before. So you probably searched for that keyword before and thus serves relevant ads to your past searches. [:)]
