Integrating MoPub with Mediation

This guide is for publishers who want to use the Google Mobile Ads SDK to load and display ads from MoPub via mediation. It covers how to add MoPub to an ad unit's mediation configuration, how to set up Ad Network Optimization (ANO), and how to integrate the MoPub SDK and adapter into an iOS app.

Supported ad formats and features

The AdMob mediation adapter for MoPub has the following capabilities:

Formats
Banner
Interstitial
Rewarded
Native
Features
Adaptive banner
Ad network optimization (ANO)

Requirements

  • iOS deployment target of 8.0 or higher
  • Latest Google Mobile Ads SDK

Step 1: Set up MoPub

First, sign up and log in to your MoPub UI. Navigate to the Apps page and click the Add a New App button.

MoPub new app

Select iOS as the Platform for your app, enter the App name and iTunes URL of your app. Then select a primary and secondary category of your app from the provided list.

MoPub app

MoPub requires you to create your first ad unit before you can finish adding your app.

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

Choose Tablet as the Device type. Choose a banner format that matches the ad size you're requesting in your app. Enter a Name for your ad unit.

The refresh rate is handled by the Google Mobile Ads SDK according to your refresh rate setting in the AdMob UI. So, we recommend using a high value for the Refresh Interval here (e.g. 1000 seconds).

Banner

Interstitial

Choose Tablet as the Device type. Choose Tablet Full Screen as the Format. Enter a Name for your ad unit. Choose the type of Layout to present the ad in.

Interstitial

Native

Choose Tablet as the Device type. Choose Native (Custom layout) as the Format. Enter a Name for your ad unit.

Interstitial

Click Save and View Code Integration to get your Ad Unit ID.

MoPub ad unit id

In addition to the Ad Unit ID, you'll also need to obtain your MoPub API Key and Inventory Report ID to set up your AdMob ad unit ID. To find your API Key and Inventory Report ID, navigate to the Reports page and click View API Access Details.

MoPub reporting keys

MoPub Marketplace

To get ads from MoPub, your account must be approved for MoPub Marketplace. During your initial account setup, you will be prompted to go through the process for Marketplace approval. Part of this process includes entering your payment information.

MoPub marketplace

See the Marketplace setup guide for more details.

Step 2: Configure mediation settings for your AdMob ad unit

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

Next, 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 MoPub as an ad source.

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

AdMob Beta mediation tab

Enter your ad format and platform, then click Continue.

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.

New mediation group 2

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

Select ad unit

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

Mediation group ad units

Add MoPub as an ad source

In the Ad Sources card, select Add Ad Network. Then select MoPub.

Enable the Optimize switch. Enter the API Key and Inventory Report ID obtained in the previous section to set up ANO for MoPub. Then enter an eCPM value for MoPub and click Continue.

Next, enter the Ad Unit ID obtained in the previous section. Then click Done.

Configure MoPub ad unit

Finally, click Save.

Using rewarded ads

In the settings for your rewarded ad unit, provide values for the reward amount and reward type. Then, to ensure you provide the same reward to the user no matter which ad network is served, check the Apply to all networks in Mediation groups box.

Apply to all networks

If you don't apply this setting, the MoPub adapter passes back the reward specified in the MoPub dashboard.

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

Step 3: Import the MoPub SDK and adapter

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

    use_frameworks!

pod 'GoogleMobileAdsMediationMoPub'

  • From the command line run:

    pod install --repo-update

Manual integration

  • Download the latest version of the MoPub SDK and link the MoPubSDK source code in your project.
  • Download the latest version of the MoPub adapter from the download link in the Changelog and link MoPubAdapter.xcframework in your project.

Step 4: Additional code required

No Additional code required for MoPub integration.

Step 5: Test your implementation

To get test ads from MoPub, you need a guaranteed or backfill line item. MoPub recommends adding the Demo line item to your ad unit to get test ads. The Demo line item is added to your MoPub account by default.

MoPub demo item

The Demo Line Item contains test creatives for native and banner ad units by default, but does not have a test creative for interstitial ad units. To add your own test creative for interstitial ads, you need to upload a simple image to the MoPub UI by navigating to the Demo Line Item and clicking the Add a New Creative button. Choose Tablet Full Screen format. Fill the form with the necessary details and click Save to add your test creative to the Demo Line Item.

MoPub demo item

That's it! You now have a working mediation integration with MoPub.

Optional steps

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

To collect consent for MoPub, MoPub asks that you use its consent mechanism. See the MoPub GDPR Publisher Integration Guide for more information.

Using native ads

Network-specific parameters

The MoPub adapter supports an additional request parameter which can be passed to the adapter using the GADMoPubNetworkExtras class. This class includes the following property:

  • privacyIconSize - Set the size for the MoPub privacy icon in points. Values can range from 10 to 30 inclusive. The default size for the privacy icon is 20.

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

Swift

let adRequest = GADRequest()
let extras = GADMoPubNetworkExtras()
extras.privacyIconSize = 15
adRequest.registerAdNetworkExtras(extras)

Objective-C

GADRequest *request = [GADRequest request];
GADMoPubNetworkExtras *extras = [[GADMoPubNetworkExtras alloc] init];
extras.privacyIconSize = 15;
[adRequest registerAdNetworkExtras:extras];

Ad Rendering

The MoPub adapter returns its native ads as GADNativeAd objects. It populates the following Native ads field descriptions for a GADNativeAd.

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

Impression and Click Tracking

MoPub and Google Mobile Ads SDKs track impressions in their own way, so there may be discrepancies.

Clicks are detected by the Google Mobile Ads SDK and are forwarded to MoPub SDK, so click reporting will be in sync.

Error codes

If the adapter fails to receive an ad from MoPub, publishers can check the underlying error from the ad response using GADResponseInfo.adNetworkInfoArray under the following classes:

GADMAdapterMoPub
GADMediationAdapterMoPub

Here are the codes and accompanying messages thrown by the MoPub adapter when an ad fails to load:

Error code Reason
100 The MoPub SDK sent an ad load failure callback.
101 An ad is already loaded for this network configuration.
102 There was an error loading data from the network.
103 MoPub server parameters configured in the AdMob UI are missing/invalid.
104 The requested ad size does not match a MoPub supported banner size.
105 Banner ad size is smaller than minimum banner size set by the publisher.
-1,0,1-38 MoPub SDK error. See code for more details.
