What Is Ad Exchange?

top ad exchanges

Ad exchanges represent a digital marketplace connecting publishers and advertisers to sell and buy inventories. To do this, the ad exchange gathers multiple ad networks, SSPs, and publishers to create a large pool of assorted inventories.

This big pool of impressions is then presented to buyers (DSPs, advertisers, and even ad networks) so that they may purchase the impressions in real time. The pool of impressions typically includes a display, video, mobile, and in-app inventories, giving the publisher more chances to profit from their inventory by accessing global demand. However, for a publisher to have complete control of their inventory–such as setting floor prices, adding/blocking demand, and setting up targeting criteria–they must use a proxy provider.

Proxy providers allow for easy integration with ad exchanges while also giving the publisher specified control over their inventory; as such, it is recommended that publishers use proxy providers when giving their inventory to an ad exchange.
