Supply-side Platform (SSP)

A Supply-side Platform (SSP) is a technology tool used by publishers (like website owners) to manage and sell their ad space efficiently. It connects the publisher’s available ad inventory to multiple ad networks and demand-side platforms (DSPs), allowing automated, real-time auctions where advertisers bid to display their ads. This helps publishers maximize their revenue by ensuring their ad spaces are sold to the highest bidders, while advertisers get targeted ad placements. Essentially, an SSP acts as a middleman that streamlines and optimizes the process of monetizing online content through programmatic advertising.
