What Is Open Exchange?
An open exchange is a digital marketplace where ad impressions are bought and sold through real-time bidding (RTB). It operates similarly to a stock exchange, where multiple buyers (advertisers) and sellers (publishers) participate in auctioning ad space.
The Importance Of Open Exchange
Open exchanges provide a vast inventory of ad spaces, making it easier for advertisers to reach a broader audience. They democratize access to digital advertising by allowing smaller advertisers to compete with larger ones.
Types Of Open Exchange
General Open Exchanges: Platforms open to all buyers and sellers.
Private Marketplaces (PMPs): Restricted access marketplaces where only selected advertisers can bid on premium inventory.
Examples Of Open Exchange
- Google Ad Exchange
- AppNexus
- Rubicon Project
