If you have an adwords account you can choose to create a keyword or site targeted campaign. If you choose a site targeted campaign you canchoose which website your ad will appear and then you select how much you want to pay as a maximum for 1000 impressions of your ad. The adsense publishers get paid a fraction of the impression they give you.
