Impression-level ad revenue

When an impression occurs, Next Gen Mobile Ads SDK provides ad revenue data associated with that impression. You can use the data to calculate a user's lifetime value, or forward the data downstream to other relevant systems.

This guide is intended to help you implement the impression-level ad revenue data capture in your Android app.

Prerequisites

Each ad format has an onAdPaid event callback. During the lifecycle of an ad event, Next Gen Mobile Ads SDK monitors impression events and invokes the handler with an earned value.

The following example handles paid events for a rewarded ad:

Kotlin

ad.adEventCallback =
  object : RewardedAdEventCallback {
    override fun onAdPaid(adValue: AdValue) {
      // Send the impression-level ad revenue information to your
      // preferred analytics server directly within this callback.

      // Extract the impression-level ad revenue data.
      val valueMicros = adValue.valueMicros
      val currencyCode = adValue.currencyCode
      val precisionType = adValue.precisionType

      val loadedAdSourceResponseInfo = ad.getResponseInfo().loadedAdSourceResponseInfo
      val adSourceName = loadedAdSourceResponseInfo?.name
      val adSourceId = loadedAdSourceResponseInfo?.id
      val adSourceInstanceName = loadedAdSourceResponseInfo?.instanceName
      val adSourceInstanceId = loadedAdSourceResponseInfo?.instanceId
      val extras = ad.getResponseInfo().responseExtras
      val mediationGroupName = extras.getString("mediation_group_name")
      val mediationABTestName = extras.getString("mediation_ab_test_name")
      val mediationABTestVariant = extras.getString("mediation_ab_test_variant")
    }
  }

Java

ad.setAdEventCallback(
    new RewardedAdEventCallback() {
      @Override
      public void onAdPaid(@NonNull AdValue value) {
        // Send the impression-level ad revenue information to your preferred
        // analytics server directly within this callback.

        // Extract the impression-level ad revenue data.
        long valueMicros = value.getValueMicros();
        String currencyCode = value.getCurrencyCode();
        PrecisionType precisionType = value.getPrecisionType();

        AdSourceResponseInfo loadedAdSourceResponseInfo =
            ad.getResponseInfo().getLoadedAdSourceResponseInfo();
        String adSourceName = loadedAdSourceResponseInfo.getName();
        String adSourceId = loadedAdSourceResponseInfo.getId();
        String adSourceInstanceName = loadedAdSourceResponseInfo.getInstanceName();
        String adSourceInstanceId = loadedAdSourceResponseInfo.getInstanceId();

        Bundle extras = ad.getResponseInfo().getResponseExtras();
        String mediationGroupName = extras.getString("mediation_group_name");
        String mediationABTestName = extras.getString("mediation_ab_test_name");
        String mediationABTestVariant = extras.getString("mediation_ab_test_variant");
      }
    });

Identify a custom event ad source name

For custom event ad sources, the AdSourceResponseInfo.name property returns the ad source name Custom event. If you use multiple custom events, the ad source name isn't granular enough to distinguish between multiple custom events. To locate a specific custom event, do:

  1. Get theAdSourceResponseInfo.name property.
  2. Set a unique ad source name.

The following example sets a unique ad source name for a custom event:

Kotlin

private fun getUniqueAdSourceName(loadedAdapterResponseInfo: AdSourceResponseInfo): String {
  var adSourceName = loadedAdapterResponseInfo.name
  if (adSourceName == "Custom Event") {
    if (
      loadedAdapterResponseInfo.adapterClassName ==
        "com.google.ads.mediation.sample.customevent.SampleCustomEvent"
    ) {
      adSourceName = "Sample Ad Network (Custom Event)"
    }
  }
  return adSourceName
}

Java

private String getUniqueAdSourceName(@NonNull AdSourceResponseInfo loadedAdapterResponseInfo) {
  String adSourceName = loadedAdapterResponseInfo.getName();
  if (adSourceName.equals("Custom Event")) {
    if (loadedAdapterResponseInfo
        .getAdapterClassName()
        .equals("com.google.ads.mediation.sample.customevent.SampleCustomEvent")) {
      adSourceName = "Sample Ad Network (Custom Event)";
    }
  }
  return adSourceName;
}

Implementation best practices

  • Set the listener immediately once you create or get access to the ad object, and definitely before showing the ad. This makes sure that you don't miss any paid event callbacks.
  • Send the impression-level ad revenue information to your preferred analytics server immediately at the time the paid event callback is called. This makes sure that you don't accidentally drop any callbacks and avoids data discrepancies.

AdValue

AdValue is a class that represents the monetary value earned for an ad, including the value's currency code and its precision type encoded as follows.

PrecisionType Description
UNKNOWN An ad value that's unknown. This gets returned when LTV pingback is enabled but there isn't enough data available.
ESTIMATED An ad value estimated from aggregated data.
PUBLISHER_PROVIDED A publisher provided ad value, such as manual CPMs in a mediation group.
PRECISE The precise value paid for this ad.
In case of mediation, Ad Manager tries to provide an ESTIMATED value for ad sources that have automatic data collection enabled. For non-optimized ad sources, or in cases where there aren't enough aggregated data to report a meaningful estimation, the PUBLISHER_PROVIDED value is returned.

Test impressions from Open Bidding

After an impression-level ad revenue event occurs for an Open Bidding ad source through a test request, you receive only the following values:

  • UNKNOWN: indicates the precision type.
  • 0: indicates the ad value.

Previously, you might have seen the precision type as a value other than UNKNOWN and an ad value more than 0.
