Open Bidding
Invited third-party demand partners compete for your inventory in a single auction with real-time, server-to-server bidding. Here’s an overview of the setup:
- Each publisher and demand partner must have an established contractual relationship with one another.
- Publishers create a company for each demand partner, and then target inventory with a yield group.

SDK Bidding
Allowed third-party buyers buy your mobile app inventory and render creatives in your app by using an SDK owned by the buyer (as opposed to using the GMA SDK). Here’s an overview of the setup:
- Install the buyer's SDK in your mobile app.
- Allow SDK Bidding, enabling secure signals, and adding ad unit mappings for the mobile inventory and formats you want to support.
