How Do SSPs Work?

Supply-side platforms (SSPs) play a crucial role in connecting publishers with demand partners and optimizing ad revenue. By understanding how SSPs work, publishers can make informed decisions when choosing the best software for their needs.

When a webpage is loaded, the SSP sends ad requests to various demand-side platforms (DSPs) through ad exchanges. These DSPs then bid to display ads to the page’s visitor. The SSP evaluates the bids and selects the highest paying one to forward to the respective ad server. The final decision on which ad to display is made by the ad server based on the publisher’s configuration.

It is important to note that different SSPs offer unique functionalities and services, which can be compared and evaluated to find the best software for publishers’ specific requirements. Let’s dive deeper into the functionality and features of some of the leading SSP software providers.
