I would say they sell access to you for advertising. As an advertiser, you designate how many people you would like to targeted for your adverstising, based on your requested triggers/demographics. Google takes your order, and presents the ads to their users. It's not like they take the order, and then present the infomation to the advertiser to be used. They (Google) take the request and serve the ads provided by the advertiser to the people that they decide should see it based on the information that they (again Google) have.
