Demand Side Platform (DSP)

A Demand Side Platform (DSP) is a core technology used by advertisers to automate and optimize digital ad buying across multiple channels.

Definition

A Demand Side Platform (DSP) is a software system that enables advertisers to purchase digital advertising inventory programmatically from multiple sources such as ad exchanges and supply-side platforms. It automates the decision-making process for buying impressions, often using real-time bidding (RTB) to evaluate and bid on ad opportunities within milliseconds. DSPs allow advertisers to define targeting criteria, control budgets, and optimize campaigns using data-driven insights. By centralizing campaign management and leveraging algorithms, DSPs improve efficiency and precision in reaching specific audiences.
