What are Supply-Side Platforms (SSP) in the USA?

Supply-Side Platforms (SSPs) are technology platforms that help publishers manage and optimize the monetization of their digital advertising inventory. These platforms connect publishers with multiple demand sources, such as ad exchanges, demand-side platforms (DSPs), and direct advertisers, to maximize ad revenue. SSPs enable real-time bidding (RTB), allowing advertisers to bid on ad space in real time based on audience data, and automatically serve the highest-paying ads. They also offer features such as inventory management, ad targeting, and reporting to help publishers track performance and optimize ad delivery. By increasing competition for ad space and providing advanced analytics, SSPs help publishers get the most out of their available ad inventory.
