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 18.1.0 . This and later versions of the Mobile Ads SDK integrates with the Open Measurement (OM) SDK to enable third-party viewability measurement.
The Google Mobile Ads SDK supports OM SDK version 1.4.
Prerequisites
- Google Mobile Ads SDK 18.1.0 or higher.
- Complete the Get started guide.
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
Ensure that transparent overlays are non-obstructing
For an ad to not be considered blocked, the view that is obscuring the ad must have one of these settings:
alpha = 0, or,
visibility = View.GONEorvisibility = View.INVISIBLE
It doesn't matter if the obscuring view has a transparent background—the view's alpha and visibility values are what determine whether the view is blocking your ad.
If the Open Measurement SDK detects an obstruction over the ad, it could impact
whether a viewability provider considers the impression viewable. To fix this,
set your view's alpha to 0 or
set the visibility to View.GONE or View.INVISIBLE.
Troubleshooting
Be aware of the following when implementing Open Measurement:
- No support for AdMob campaigns.
You must check with the mediation partner to learn if they support Open Measurement for ads they render.
Ads that are obscured by overlaying views might not register viewability measurements. For more information, refer to Ensure that transparent overlays are non-obstructing.
On test devices, including the Android simulator, the Test Ad label is detected as non-obstructing to the ad view.
