Measure ad revenue

Measuring your revenue sources helps you understand the lifetime value of your users and grow your app business. This guide shows you how to set up ad revenue measurement for your platform.

After you've set up ad revenue measurement, you can then do any of the following:

Before you begin

If you haven't already, make sure to complete the following tasks:

  1. Set up your project and app as described in Get Started with Analytics.

  2. Make sure that you've linked your Firebase project to a Google Analytics account.

  3. Ensure that you've included in your app the Android SDK v17.6.0+ or the Apple platforms SDK v6.34.0+.

Implementation

You can use Google Analytics to measure ad revenue generated from displaying ads with monetization platforms, such as AdMob, AppLovin, and ironSource. To measure ad revenue, you must log ad_impression events whenever your user sees an advertisement in your app. These events contain details such as the ad platform, source, currency, and value.

AdMob

If you are using the AdMob platform, link your AdMob app to Firebase and Analytics to enable automatic measurement of ad revenue. The Firebase SDK for Google Analytics automatically logs the ad_impression event whenever your users see an ad impression.

Other ad monetization platforms

Platforms such as AppLovin and ironSource provide impression-level revenue data that you can then use to log Google Analytics ad_impression events.

The following sections show implementation examples for a few different ad monetization platforms.

AppLovin

Swift

func didPayRevenue(_ impressionData: MAAd?) {
  if let impressionData = impressionData {
    Analytics.logEvent(
      AnalyticsEventAdImpression,
      parameters: [
        AnalyticsParameterAdPlatform: "AppLovin",
        AnalyticsParameterAdUnitName: impressionData.adUnitIdentifier,
        AnalyticsParameterAdFormat: impressionData.format,
        AnalyticsParameterValue: impressionData.revenue,
        AnalyticsParameterCurrency: "USD",  // All Applovin revenue is sent in USD
        AnalyticsParameterAdSource: impressionData.networkName,
      ])
  }
}

Implementation considerations

To allow Google Ads to process your ad_impression, make sure to include both the currency and the value parameters (described below). Both parameters should be as accurate as possible to prevent over-valuing or under- valuing users.

Currency parameter

The currency parameter (iOS+ | Android | Unity) should be sent as a string in a three-letter ISO_4217 format (for example, "USD"). Some ad monetization platforms omit currency, which may require you to hardcode the parameter.

Value parameter

The value parameter (iOS+ | Android | Unity) should be sent using a dot as the decimal separator. You may need to transform the values received from some platforms to fit the required format above. Some platforms localize numerical formats and use commas as decimal separators. In some cases, a platform may not send a value at all.

Additionally, the value should be a numerical type such as a double or long. For example, 1000.01, 0.001 and 1.00 are all valid

Validation

Google Analytics offers multiple features to validate your implementation throughout the development cycle.

  1. DebugView
    When first testing your implementation, use DebugView to see your test ad_impression data in the console. When you select an ad_impression event, you can review the parameters that you're sending in the Parameters panel (in the right-side of the screen). This helps you confirm that the correct information is being processed.

  2. Realtime
    Once you have deployed your app, use the Google Analytics Realtime report to confirm the implementation is working correctly. In the Realtime report, view the Event count by Event name card and select ad_impression to see the event and parameter details for the last 30 minutes.

  3. BigQuery
    Use BigQuery export to extract a sample of one or more days of ad_impression events. Use this extracted sample to look for issues, such as zero or not set values, and apply fixes to your code for any unhandled use cases.

Next steps

Visit your Analytics dashboard in the Firebase console or in your linked Analytics property in the Analytics console. Ad revenue is factored into metrics, such as Average Revenue Per User (ARPU) and Lifetime Value (LTV).
