AdMob Mediation is a feature that lets you serve ads to your apps from multiple sources, including the AdMob Network, third-party ad networks, and AdMob campaigns. AdMob Mediation helps maximize your fill rate and increase your monetization by sending ad requests to multiple networks to ensure you find the best available network to serve ads. Case study.
This guide is your one stop shop for integrating mediation into your AdMob app. It covers both bidding and waterfall integrations.
Prerequisites
Before you can integrate mediation for an ad format, you need to integrate that ad format into your app:
New to mediation? Read Overview of AdMob mediation.
For bidding: Google Mobile Ads Unity plugin 4.2.0 or higher.
Initialize the Mobile Ads SDK
The quick start guide shows you how to initialize the Mobile Ads SDK. During that initialization call, mediation and bidding adapters also get initialized. It is important to wait for initialization to complete before you load ads in order to ensure full participation from every ad network on the first ad request.
The sample code below shows how you can check each adapter's initialization status prior to making an ad request.
using GoogleMobileAds.Api;
using System.Collections.Generic;
...
public class GoogleMobileAdsDemoScript : MonoBehaviour
{
...
public void Start()
{
// Initialize the Mobile Ads SDK.
MobileAds.Initialize((initStatus) =>
{
Dictionary<string, AdapterStatus> map = initStatus.getAdapterStatusMap();
foreach (KeyValuePair<string, AdapterStatus> keyValuePair in map)
{
string className = keyValuePair.Key;
AdapterStatus status = keyValuePair.Value;
switch (status.InitializationState)
{
case AdapterState.NotReady:
// The adapter initialization did not complete.
MonoBehaviour.print("Adapter: " + className + " not ready.");
break;
case AdapterState.Ready:
// The adapter was successfully initialized.
MonoBehaviour.print("Adapter: " + className + " is initialized.");
break;
}
}
});
...
}
}
