An agency trading desk (ATD) is a team or department within an advertising agency that is responsible for managing and optimizing the agency's programmatic advertising campaigns. Agency trading desks are typically integrated into demand-side platforms (DSPs), which are used to buy and manage digital ad inventory from a variety of sources, such as ad exchanges, networks, and publishers.
Agency trading desks use data and technology to identify the most effective way to reach and engage with a given target audience. This may involve using data on consumer behavior, demographics, and interests to target specific groups of users, or using algorithms to automatically optimize bids and placements in real-time. Agency trading desks also often provide reporting and analytics on the performance of programmatic campaigns, and can provide insights and recommendations on how to improve their effectiveness.
