A Sell-Side Platform (SSP) – is a technology platform with the single mission of enabling publishers to manage their ad impression inventory and maximize revenue from digital media. As such they offer an efficient, automated and secure way to tap into the different sources of advertising income that are available, and provide insight into the various revenue streams and audiences.
Many of the larger web publishers of the world use a Sell Side Platform to automate and optimize the selling of their online media space. A Demand Side Platform (DSP) is a similar technology where buyers seek online advertising inventory and the exact right target audience. Often a method called Real Time Bidding (RTB) is used to complete DSP transactions.
