GoogleAdMob Mediation Tutorial
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 house ad 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.
There are two types of mediation you can use, independently or simultaneously, in AdMob:
 Impression goal campaigns
 Ad sources ordered by eCPM
Some ad networks may allow SDK-less mediation.

How GoogleAdMob mediation work:
AdMob currently supports SDK-less mediation for certain ad networks (Android, iOS). SDK-less
mediation allows you to access demand without needing to integrate individual ad network SDKs into
your apps. This means you can access additional networks for mediation without worrying about keeping
third-party SDKs up to date.
When we configure multiple ad networks in AdMob Mediation , you have to tell AdMob in what order to
request these networks by setting their respective CPM.
Ad Network Optimization (ANO) is a feature within AdMob Mediation that enables you to generate the
highest CPM from the ad netwroks in your mediation chain. AdMediation automates the process of
ordering your mediation chain and helps your maximize revenue with minimum effort.
Choosing your Mediation networks
Google mediation supports over 30 third-party ad networks. Integrating mediation requires
changes in these places:
1. Third-party ad network UI - Sign up for the third-party ad network and create a placement in
their frontend.
2. AdMob UI - Update your ad unit's mediation settings to include the ad network. It is also
recommended that you set up ad network optimization for ad networks that support it.
3. App code - Update your app to include the third-party ad network's SDK, and an adapter library
that communicates between Google and the third-party ad network to request and serve ads.

List of AdNetwork which support GoogleAdMediation:
*Those AdNetwroks are not listed here are added with the Custom Event.

4. B y - R a k e s h P a r i h a r [ h t t p : / / r a k e s h p a r i h a r . w e e b l y . c o m ] Page 4
Custom Events:
If you're looking for an ad network and don't see it on the list above, you can
use custom events to write your own integration with that ad network.
See Custom Events for more details on how to create a custom event.
Structure of GoogleAdMobMediation:
Each AdNetwork must had a Adapter and SDK for AdMobMediation.

Once these steps are complete, see the Unity plugin API section for more information
on how to request banner and interstitial ads using the plugin.
Unity plugin API
Basic banner request
using GoogleMobileAds.Api;
…
private void RequestBanner()
{
#if UNITY_EDITOR
string adUnitId = "unused";
#elif UNITY_ANDROID
string adUnitId = "INSERT_ANDROID_BANNER_AD_UNIT_ID_HERE";
#elif UNITY_IPHONE
string adUnitId = "INSERT_IOS_BANNER_AD_UNIT_ID_HERE";
#else
string adUnitId = "unexpected_platform";
#endif
// Create a 320x50 banner at the top of the screen.
BannerView bannerView = new BannerView(adUnitId, AdSize.Banner, AdPosition.Top);
// Create an empty ad request.
AdRequest request = new AdRequest.Builder().Build();
// Load the banner with the request.
bannerView.LoadAd(request);
}

12. B y - R a k e s h P a r i h a r [ h t t p : / / r a k e s h p a r i h a r . w e e b l y . c o m ] Page 12
Basic interstitial request
using GoogleMobileAds.Api;
…
private void RequestInterstitial()
{
#if UNITY_ANDROID
string adUnitId = "INSERT_ANDROID_INTERSTITIAL_AD_UNIT_ID_HERE";
#elif UNITY_IPHONE
string adUnitId = "INSERT_IOS_INTERSTITIAL_AD_UNIT_ID_HERE";
#else
string adUnitId = "unexpected_platform";
#endif
// Initialize an InterstitialAd.
InterstitialAd interstitial = new InterstitialAd(adUnitId);
// Create an empty ad request.
AdRequest request = new AdRequest.Builder().Build();
// Load the interstitial with the request.
interstitial.LoadAd(request);
}
Ad events
private void RequestBanner()
{
BannerView bannerView = new BannerView(adUnitId, AdSize.Banner, AdPosition.Top);
// Called when an ad request has successfully loaded.
bannerView.OnAdLoaded += HandleOnAdLoaded;
// Called when an ad request failed to load.
bannerView.OnAdFailedToLoad += HandleOnAdFailedToLoad;
// Called when an ad is clicked.
bannerView.OnAdOpened += HandleOnAdOpened;
// Called when the user returned from the app after an ad click.
bannerView.OnAdClosed += HandleOnAdClosed;
// Called when the ad click caused the user to leave the application.
bannerView.OnAdLeavingApplication += HandleOnAdLeavingApplication;
}
public void HandleOnAdLoaded(object sender, EventArgs args)
{
print("OnAdLoaded event received.");
// Handle the ad loaded event.
}
Rewarded Video
Rewarded video ads allow publishers to offer the user something of value in exchange for
engaging with advertising content.

13. B y - R a k e s h P a r i h a r [ h t t p : / / r a k e s h p a r i h a r . w e e b l y . c o m ] Page 13
Basic rewarded video ad request
private void RequestRewardBasedVideo()
{
#if UNITY_EDITOR
string adUnitId = "unused";
#elif UNITY_ANDROID
string adUnitId = "ca-app-pub-3940256099942544/5224354917";
#elif UNITY_IPHONE
string adUnitId = "ca-app-pub-3940256099942544/1712485313";
#else
string adUnitId = "unexpected_platform";
#endif
RewardBasedVideoAd rewardBasedVideo = RewardBasedVideoAd.Instance;
AdRequest request = new AdRequest.Builder().Build();
rewardBasedVideo.LoadAd(request, adUnitId);
}
Rewarded video ad events
RewardBasedVideoAd provides ad events to notify you about an ad's lifecycle. These events are of type
EventHandler. This example demonstrates how to register for ad events on a rewarded video ad:
// Reward based video instance is a singleton. Register handlers once to
// avoid duplicate events.
if (!rewardBasedEventHandlersSet)
{
// Ad event fired when the rewarded video ad
// has been received.
rewardBasedVideo.OnAdLoaded += HandleRewardBasedVideoLoaded;
// has failed to load.
rewardBasedVideo.OnAdFailedToLoad += HandleRewardBasedVideoFailedToLoad;
// is opened.
rewardBasedVideo.OnAdOpening += HandleRewardBasedVideoOpened;
// has started playing.
rewardBasedVideo.OnAdStarted += HandleRewardBasedVideoStarted;
// has rewarded the user.
rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;
// is closed.
rewardBasedVideo.OnAdClosed += HandleRewardBasedVideoClosed;
// is leaving the application.
rewardBasedVideo.OnAdLeavingApplication += HandleRewardBasedVideoLeftApplication;
rewardBasedEventHandlersSet = true;
}

Using Rewarded Video Ads
In the settings for your rewarded video ad unit, check the Override reward settings from third-
party ad networks when using AdMob mediation so that you provide the same reward to the
user no matter which ad network is served.
If you don't override the reward, the Third Party Ads Network adapter passes back the reward
specified in the Third Party Ads Network UI.
For more information on setting reward values for AdMob ad units, see Create an ad unit.
Chartboost:
Download the latest version of the Chartboost SDK. Find the chartboost.jar file under lib/ folder
and add it to your project's libs folder (create a libs folder and add the jar file if you don't have one).
Step1: SetUp Chartboost
