What is an SSP?

SSP stands for Supply Side Platform.

An SSP is a software platform that helps digital publishers and app developers sell their ad inventory (i.e., the available advertising space on their websites or apps) to advertisers through automated auctions.

An SSP is typically used by publishers to connect their inventory to multiple ad exchanges, demand-side platforms (DSPs), and other buyers.

The platform enables publishers to manage their ad inventory, set pricing rules, and optimize revenue by selecting the most profitable ad placements.

SSPs often include features such as real-time bidding (RTB), data analytics, and reporting tools to help publishers monitor their performance and make informed decisions about their inventory.


SSPs are a key component of the programmatic advertising ecosystem, which allows for the automated buying and selling of digital ad space.
