What is an Ad Exchange?
An ad exchange is an online marketplace where advertising space is bought and sold in real-time. Ad exchanges enable publishers to sell their ad space to the highest bidder, while advertisers can purchase inventory from multiple sources in a single transaction. This enables both sides to optimize their return on investment (ROI) by setting the most appropriate prices for their inventory.
How does an Ad Exchange work?
Ad exchanges work by connecting publishers and advertisers in a single, real-time platform. Publishers can list their available ad space, and advertisers can bid on it. The highest bidder then wins the ad space, and the publisher is paid for it. Ad exchanges also provide access to a wide range of targeting options and ad formats, allowing advertisers to optimize their campaigns.
Benefits of an Ad Exchange
Ad exchanges offer a number of benefits for both publishers and advertisers.
- For Publishers:
- Increased competition for ad space, resulting in higher CPMs (cost per thousand impressions).

- For Advertisers:
