Use Unity LevelPlay in-app bidding to sell your ad inventory in an automated auction by allowing ad sources to simultaneously bid for each impression in real time.
You can set up an environment that includes only bidding sources, only non-bidding sources, or a combination of both (a hybrid model).
- Bidding sources place a real-time bid for each impression.
- Non-bidding sources bid by using eCPM, which is based on historical performance.
- In the hybrid model, both bidding and non-bidding sources are competing for all ad impressions.
