On the Exchange page, you choose the exchanges you want the tactic to use.
How It Works
the DSPis a Demand Side Platform (DSP) that plugs into large ad exchanges, or Supply Side Platforms (SSPs) (i.e. Rubicon, Google, and Pubmatic), and makes their publisher inventory available to your tactic. Each time an impression becomes available on one of the exchanges it is available to users of the DSP through an auction/bidding model. When an impression becomes available, your tactic bids on that impression. The winning bid will be placed on the exchange, and the winning advertiser to bid against other DSPs on that exchange. If that advertiser has the highest bid, the impression will be delivered.
