Demand-Side Platform (DSP)

A Demand-Side Platform (DSP) is software that enables advertisers and agencies to buy digital ad inventory programmatically across multiple ad exchanges and supply sources through a single interface. DSPs allow buyers to set targeting parameters, budgets, and bidding strategies, then automatically purchase impressions via real-time bidding. Leading DSPs include The Trade Desk, Amazon DSP, and Google's Display & Video 360 (DV360).
