Demand-Side Platform (DSP)

A platform used by advertisers or agencies to buy and optimize digital advertising inventory across exchanges and publishers.


BUSINESS RELEVANCE

A DSP gives advertisers one place to buy, target and measure programmatic media across many exchanges, so the choice of DSP affects inventory access, data use, fees and transparency.


IMPLEMENTATION EXAMPLE

An agency sets up a Display & Video 360 campaign with a $40,000 budget, first-party audience lists, a $12 maximum CPM and frequency cap of five per week, and buys across open exchanges and two private marketplace deals.


LIMITATIONS

DSP fees, data costs and supply-path layers reduce the share of budget that reaches publishers. Optimization targets such as clicks or viewable impressions can favor low-quality inventory, and signal loss limits audience targeting.


TECHNICAL EXPLANATION

A DSP connects to ad exchanges and supply-side platforms, receives bid requests in real time, evaluates each impression against campaign targeting, budgets, pacing and frequency rules, and uses bidding algorithms to price it. It integrates audience data, creative serving and reporting, and supports open auctions, private marketplaces and programmatic guaranteed deals.
