Choose ad sources
Once you've set up AdMob Mediation, you can choose which ad sources to use. Ad sources are third-party ad networks that can serve ads through AdMob Mediation.
Supported ad sources
AdMob Mediation supports a wide range of ad sources. See the list of integrated ad sources for details on each network.
Choosing ad sources
When choosing ad sources, consider:
- Fill rate: How well the ad source fills ad requests in your target regions
- eCPM: The effective cost per mille (thousand impressions) the ad source provides
- Ad formats: Which ad formats the ad source supports
- Integration complexity: How easy it is to integrate the ad source
Bidding vs Waterfall
AdMob Mediation supports two integration methods:
- Bidding: Ad sources compete in real-time for your ad inventory. This is the recommended method.
- Waterfall: Ad sources are prioritized in a sequential order.
