Requirements

  • Xcode 8.0 or higher
  • iOS Deployment target of 6.0 or higher
  • Minimum required Google Mobile Ads SDK 7.12.0 or higher

Step 1: Set up Facebook Audience Network

First, sign up and log in to your Facebook developer account. Navigate to My Apps page by clicking on the My Apps button on the top right corner.

My apps screen

Add your app to the Facebook console by clicking the Add a New App button.

Add new app ID

Fill out the form and click Create App ID to add your app to Facebook.

Add product screen

Next, in the Facebook dashboard for your app, add Facebook Audience Network to your app by clicking the Add Product under PRODUCTS on the left sidebar and clicking Set Up for Audience Network.

Get started screen

Once your app is added you will be taken to the Audience Network Apps screen. Click Get Started to create an Ad Space.

Ad spaces screen

To create a new Ad Space click the Create Ad Space button.

Fill out the form and click Create when done.

Once the Ad Space has been created you'll be prompted to create a new Placement. We recommend creating a new placement for mediation with AdMob even if you have one already.

Click the Create Placement button to create a new placement.

For additional instructions on creating an ad placement, select the tab corresponding to your preferred ad format.

Banner

Enter your placement's Name and Steps to Trigger an Ad when prompted.

Select Banner as the Display Format. Toggle the Refresh Rate Handled by Mediation switch to Yes and set how you want to optimize your ads. Double-check that the Status dropdown at the top of the form is set to Enabled, then click Save to create your placement.

Interstitial

Enter your placement's Name and Steps to Trigger an Ad when prompted.

Select Interstitial (App Only) as the Display Format. Set how you want to optimize your ads. Double-check that the Status dropdown at the top of the form is set to Enabled, then click Save to create your placement.

Rewarded

Enter your placement's Name and Steps to Trigger an Ad when prompted.

Select Rewarded Video as the Display Format. Set how you want to optimize your ads. Double-check that the Status dropdown at the top of the form is set to Enabled, then click Save to create your placement.

Native

Enter your placement's Name and Steps to Trigger an Ad when prompted.

Select Native as the Display Format. Click Show advanced options to reveal more options. Toggle the Carousel Ads switch and Video Ads switch to Off. Set how you want to optimize your ads. Double-check that the Status dropdown at the top of the form is set to Enabled, then click Save to create your placement.

Once the Ad Placement is created, locate the Placement ID by navigating to your new Placement's details (located under your Ad Space).

In addition to the Placement ID, you'll also need the Facebook App Access Token to set up your iOS ad unit ID for mediation.

To get your App Access Token, navigate to Facebook Access Token Tool under Tools & Support in the Facebook developer dashboard.

Step 2: Configure mediation settings for your AdMob ad unit

You need to add Facebook to the mediation configuration for your ad unit. First sign in to your AdMob account.

Next, follow the instructions for either AdMob or AdMob Beta depending on which version of the AdMob UI you're using.

AdMob

Navigate to the Monetize tab and select your app from the list of All apps on the left-hand side. A list of ad units associated with your application will be shown.

Mediation ad source

Click the link in the mediation column for the ad unit you'd like to configure with Facebook.

You will be taken to the ad unit's Mediation page.

New ad network

Click NEW AD NETWORK.

A list of supported ad networks will be shown.

Select FB

Select Facebook Audience Network from the list of networks provided and enter the Placement ID obtained in the previous section.

Enter the App Access Token obtained in the previous section. Review and check the Authorization checkbox to set up Ad Network Optimization (ANO) for Facebook Audience Network.

Click Continue at the bottom of the page to complete adding the network. Enter an eCPM value for Facebook Audience Network and click Save.

AdMob Beta

Navigate to the Mediation tab. If you have an existing mediation group you'd like to modify, click the name of that mediation group to edit it, and skip ahead to Add Facebook Audience Network as an ad source.

Mediation details

To create a new mediation group, select Create Mediation Group.

Mediation group

Enter your ad format and platform, then click Continue.

Mediation group 2

Give your mediation group a name, and select locations to target. Next, set the mediation group status to Enabled. Then click Add Ad Units, which will open up the ad unit selection overlay.

Select ad unit

Associate this mediation group with your existing AdMob ad unit. Then click Done.

You should now see the ad units card populated with the ad units you selected.

Group ad units

Add Facebook Audience Network as an ad source

In the Ad Sources card, select Add Ad Network.

Select Facebook Audience Network. Enable the Optimize switch. Enter your App Access Token obtained in the previous section. Review and check the Authorization checkbox to set up Ad Network Optimization (ANO) for Facebook Audience Network. Then enter an eCPM value for Facebook Audience Network and click Continue.

Enter the Placement ID obtained in the previous section. Then click Done.

Finally, click Save.

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 Facebook adapter defaults to a reward of type "" (empty string) with value 1. The Facebook SDK does not provide specific reward values for its rewarded video ads.

For more information on setting reward values for AdMob ad units, see Create an ad unit.

Step 3: Import the Facebook Audience Network SDK and adapter

  • Add the following line to your project's Podfile:

    pod 'GoogleMobileAdsMediationFacebook'

  • From the command line run:

    pod install --repo-update
    

Manual integration

Step 4: Additional code required

No additional code required for Facebook integration.

Step 5: Test your implementation

Facebook ads can be tested by adding the tester's Facebook account as a Tester under the Roles tab on the left-hand side in your Facebook app's dashboard (Administrator or Developer role will also be able to test the ads). The tester will need to sign in to the Facebook app on a test device to begin testing. See the Testing Audience Network Implementation guide for more details.

Add testers

That's it! You now have a working mediation integration with Facebook's Audience Network.

Optional steps

Using native ads

Some Facebook native ad assets do not map one to one to Google native ad assets. Such assets are passed back to you in the extraAssets property of GADNativeAd. Here's a code example showing how to extract these assets:

NSString *subTitle = nativeAppInstallAd.extraAssets[GADFBSubtitle];
NSString *socialContext = nativeAppInstallAd.extraAssets[GADFBSocialContext];

Network-specific parameters

The Facebook adapter supports additional request parameters which can be passed to the adapter using the GADFBNetworkExtras class. This class includes the following properties:

  • adChoicesExpandable - Indicates whether the AdChoices icon should be expandable. Default is YES.
  • adChoicesBackgroundShown - Indicates whether the AdChoices icon background mask should be shown or a transparent mask should be used instead. Default is YES.

Here's a code example of how to set this parameter at ad request:

GADRequest *adRequest = [GADRequest request];
GADFBNetworkExtras *fbExtras = [[GADFBNetworkExtras alloc] init];
fbExtras.adChoicesExpandable = NO;
fbExtras.adChoicesBackgroundShown = YES;
[adRequest registerAdNetworkExtras:fbExtras];

Ad Rendering

The Facebook adapter populates the following Native App install ad display fields for a NativeAppInstallAd:

Field Populated by Facebook adapter
Headline
Image
Body
App icon
Call to action
Star rating
Store
Price

The Facebook adapter is built to return app install ads via Google mediation. Facebook does not return content ads. However, the Facebook adapter requires both App Install ads and Content ads to be requested.

Impression and Click Tracking

Google Mobile Ads SDK uses the Facebook Audience Network SDK's callbacks for impression and click tracking, so the reports on both the dashboard should matchup with little to no discrepancies.
