Site Targeting
This is similar to Content Match, however here you pay for the number of displays your advert gets (rather than paying per click) and you can choose the sites on which you wish your ads to display.
These sites are not obliged to display your adverts, and if the CPM price you bid is too low, or the site administrator chooses not to accept your adverts, then they won’t display. So for example, if you try to set up a campaign that displays your adverts on a rival book sellers website, the chances are high that they will refuse your ads.
