Which platform serves as an intermediary between advertisers and multiple ad exchanges?

A Demand-Side Platform (DSP) acts as an intermediary between advertisers and multiple ad exchanges, facilitating the buying of digital advertising space. Using a DSP, advertisers can manage their campaigns and analyze performance across various ad exchanges simultaneously, which allows for more efficient media buying.

The primary function of a DSP is to allow advertisers to purchase ad space in real-time through software, optimizing their budgets and targeting capabilities. This integration streamlines the process of media buying by enabling access to a wider range of inventory from various exchanges through a single platform.

While other options such as supply-side platforms (SSP) and ad networks play vital roles in the advertising ecosystem, they serve different functions. SSPs focus on helping publishers sell their ad inventory, and ad networks aggregate inventory from various publishers to sell to advertisers, but they do not provide the same level of direct access to a multitude of exchanges as a DSP does. An analytics platform, on the other hand, is designed for measurement and insight generation rather than facilitating the buying process.
