Inventory targeting determines the environments and supply sources where a Campaign or Line is eligible to serve. Inventory settings should align with the Line’s media strategy, Creatives, Devices, Deals, and other targeting requirements.

Inventory Type

• Web: Ads serve within web browsers across supported desktop, laptop, and mobile environments.
• In App: Ads serve within supported applications.
• Combined: Includes both Web and In App inventory on the same Line.
  • Combined allows the Line to receive both Web and In App inventory; it does not require an individual bid request to contain both a Site Domain and App Bundle.

The selected Inventory Type should align with other Line settings:

• Site Lists are used with Web inventory.
• App Lists are used with In App inventory.
• Deals should support the selected Inventory Type.
• Device Types should align with the devices observed in the available inventory.
• Media Type and Creative Type should align with the inventory available through the targeted Deals.

Inventory Source

• Open Exchange: Inventory made available through supply-side platforms (SSPs) in an open real-time bidding marketplace across many publishers.
  • A Line can access Open Exchange inventory without targeting a Deal.
• Private Marketplace (PMP) Deals: Publisher-defined inventory made available through a private auction using a Deal ID.
• Programmatic Guaranteed (PG) Deals: Direct publisher agreements with fixed pricing and guaranteed inventory volume. Targeting and delivery requirements are primarily defined by the publisher.

Inventory sources can be further refined using Sites, Apps, Deals, Deal Lists, Exchanges, Device Types, Audiences, Geography, and other Campaign or Line targeting settings.

How Inventory Eligibility Works

Inventory eligibility is determined by all applicable Campaign and Line settings working together. Each additional targeting setting further refines the inventory that is eligible to receive a bid.

For example, a Line may first be limited by its Inventory Type, then further restricted by the selected Inventory Source, Deals, Sites or Apps, Exchanges, Device Types, Media Type, and other targeting requirements.

Eligible Inventory

An incoming bid request must satisfy all applicable targeting requirements to remain eligible. Adding more targeting does not expand available inventory; it further restricts the set of requests that can qualify.

Campaign level and Line level targeting are also evaluated together. If an inventory requirement is configured at both levels, the settings must be compatible for inventory to remain eligible.
