Quick Definition
A Demand-Side Platform (DSP) is a technology platform that enables advertisers and agencies to purchase digital advertising inventory programmatically across multiple publishers, exchanges, and ad networks. DSPs provide a single interface for advertisers to manage programmatic advertising campaigns: defining targeting criteria, setting budgets and bids, managing campaigns, and analyzing performance. DSPs connect to multiple supply-side platforms (SSPs) and ad exchanges, allowing advertisers to buy inventory across the open web, private marketplaces, and direct deals. Major DSPs include The Trade Desk, MediaMath, Amazon DSP, and Google DV360.
How It Works
DSPs work by connecting advertisers to multiple supply sources: DSPs connect to multiple SSPs (representing publishers) and ad exchanges. When advertisers create campaigns, they define targeting criteria (audience, budget, bid), and the DSP automatically bids on inventory matching those criteria across connected supply sources. When users visit websites or apps, SSPs send bid requests to DSPs, DSPs evaluate based on targeting criteria and submit bids, the highest bid wins, and the ad serves. DSPs provide campaign management, optimization, and analytics in a single interface.
