Mobile Ads SDK における Open Measurement

Open Measurement is an IAB standard that allows publishers to use third-party viewability providers to verify impressions and click measurements. The Google Mobile Ads SDK for Android supports Open Measurement beginning with SDK version 18.1.1. This and later versions of the Mobile Ads SDK integrates with the Open Measurement SDK (OM SDK) to enable third-party viewability measurements.

The OM SDK is an implementation of the Open Measurement Interface Definition, which defines an API that any third-party verification provider can use to effectively measure ads served to any mobile SDK that implements that API.

Prerequisites

Implement Open Measurement

Once you've configured your viewability provider in the AdMob UI and configured your line item to use that viewability provider, you're ready to enable Open Measurement in your app. For most ad formats, there is no additional setup needed for Open Measurement to work.

The Mobile Ads SDK supports Open Measurement automatically in the following formats:

  • Banner
  • Interstitial
  • Rewarded
  • Native Unified

    Making obstructions friendly

    Views that obscure your ad must have alpha = 0 or hidden = YES. It doesn't matter if the obscuring view has a transparent background—the view's alpha and hidden values are what determine whether the view is blocking your ad. If the Open Measurement SDK detects an obstruction over the ad, it will record the view as an unfriendly obstruction. To fix this, set your view's alpha to 0 or make the view hidden.

    Troubleshooting

    Please be aware of the following when implementing Open Measurement:

    • You must check with the mediation partner to learn if they support Open Measurement for ads they render.

    • Ads that are obscured by overlying views may not register viewability measurements (refer to Making obstructions friendly).

    • On test devices, including the Android simulator, the Test Ad label is detected as a friendly obstruction to the ad view.
