In-app bidding basics

ironSource’s in-app bidding solution enables you to sell your ad inventory in an automated auction, by allowing ad sources to simultaneously bid for each impression in real time.

How does in-app bidding work?
On the ironSource mediation platform, you can set up an environment that includes only bidding sources, only non-bidding sources, or a combination of both (a hybrid model). In the hybrid model, both bidding and non-bidding sources are competing for all ad impressions. Bidding sources will place a real-time bid for each impression and non-bidding sources ‘bid’ using the eCPM which is based on historical performance.

What versions of ironSource’s SDK support in-app bidding?
Bidding is supported using ironSource SDK 6.10.0+. Each bidding network also requires a minimum adapter version.
