Integrating MoPub with Mediation

This guide is intended 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, and how to integrate the MoPub SDK and adapter into an iOS app.

Supported ad formats and features

The DFP mediation adapter for MoPub has the following capabilities:

Formats
Banners
Interstitials
Native Ad - Custom Rendering
Features
Smart banners
Automatic data collection

Requirements

  • Xcode 6.0 or higher
  • iOS Deployment target of 8.0 or higher
  • Minimum required Google Mobile Ads SDK 7.14.0 or higher

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 finishing adding your app.

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

Banner

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 DFP UI. So, we recommend using a high value for the Refresh Interval here (e.g. 1000 seconds).

Interstitial

Choose Tablet as the Device type. Choose Fullscreen Tablet as the Format. Enter a Name for your Ad Unit. Choose the type of Layout to present the ad in.

Native

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

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 DFP ad unit ID. To find your API Key and Inventory Report ID, navigate to the Reports page and click View API Access Details.

MoPub Marketplace

To get ads from MoPub, your account needs to 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.

See the Marketplace setup guide for more details.

Step 2: Configure Mediation Settings for your DFP ad unit

Sign in to your DFP account. Navigate to Delivery > Yield Groups and click the Create Yield Group button.

DFP create yield group button

Enter a Yield Group Name, select your Ad Format, and set the Environment to Mobile App. Under the Targeting section, select the ad unit ID to which you want to add mediation.

Next, click the Add Another Yield Partner button.

If you already have a Yield Partner for MoPub, you can simply select it. Otherwise, select Create a new Yield Partner.

Select MoPub as the Yield partner and enter a unique Name. Check the checkbox for Enable automatic data collection of estimated CPM to optimize Mediation to enable automatic data collection, and enter the API Key and Inventory Report ID obtained in the previous section. Click Save when done.

Once the Yield partner is chosen, select Mobile SDK mediation as the Integration type and iOS as the Operating system. Enter the Ad Unit ID obtained in the previous section. Enter a Default CPM value.

Click Save and Activate at the bottom of the page when done.

Step 3: Import the MoPub SDK and adapter

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

    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 and link MoPubAdapter.framework in your project.

Step 4: Additional code required

No additional code is 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.

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

Optional steps

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:

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

Ad Rendering

The MoPub adapter always maps a MoPub native ad to a Google NativeAppInstallAd. It populates the following Native App install ad display fields for a GADNativeAppInstallAd :

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.
