A DSP connects to supply-side platforms (SSPs) and ad exchanges, which together represent the inventory that publishers have for sale. When a user loads a page or app, an auction happens in milliseconds, and the DSP decides whether to bid – and how much – based on your targeting and bids.
Because the buying is automated and based on rules you set, a DSP lets one advertiser reach inventory across thousands of sources without manual deals. You stay in control of who you target, what you pay, and where your budget goes.
