A supply-side platform (SSP) is a technology platform that is used by publishers to manage and monetize their digital advertising inventory. An SSP is typically used by publishers to sell their advertising inventory to advertisers or ad networks, and to manage the process of ad serving, pricing, and reporting. An SSP is often integrated with a publisher's website or app, and can provide a way for publishers to manage and optimize the delivery of ads to their audience. An SSP typically includes a range of features and tools, such as inventory management, ad targeting, bidding, and analytics, that can help publishers to improve the performance and revenue of their advertising inventory. An SSP can also provide a way for publishers to connect with multiple demand-side platforms (DSPs), and to access a wider range of advertisers and ad campaigns.
