Private auctions (invitation-only)
Open auctions (available to all bidders)

Private marketplaces offer premium inventory with greater transparency. Publishers like Verizon Media use these environments to protect brand value while maintaining ad spending efficiency.

Ad Exchanges and Networks

Ad exchanges connect buyers and sellers through open marketplaces. They’re crucial components in the advertising ecosystem.

Major players include OpenX, Index Exchange, and Rubicon Project. These platforms facilitate transactions between thousands of advertisers and publishers.

Quality matters in these environments. Ad fraud prevention tools from companies like Integral Ad Science and DoubleVerify monitor for invalid traffic.

Pricing models typically include:

CPM (cost per thousand impressions)
CPC (cost per click)
Revenue shares between participants

Fee structures remain complex. The ad tech stack often includes multiple intermediaries taking percentages.

Targeting and Personalization Technologies

Behavioral Targeting

Behavioral targeting analyzes user activity to deliver relevant ads. It’s fundamental to modern online advertising platforms.

User tracking tools collect data on:
