An ad network is an intermediary that aggregates ad inventory from multiple publishers and sells it to advertisers. It simplifies the buying process by offering one point of access to thousands of websites and apps.
How Ad Networks Work
- Publishers supply their unsold ad inventory to the network
- The network packages and categorizes this inventory
- Advertisers buy inventory through the network based on targeting criteria
- The network takes a margin between publisher payout and advertiser cost
Major Ad Networks
- Google Display Network (GDN): 35M+ sites and apps
- Meta Audience Network: Extends Meta ads to third-party apps
