Open Measurement is an IAB standard that allows publishers to use third-party
viewability providers to verify impressions and click measurements.
Google Mobile Ads SDK
supports Open Measurement starting with version
7.43.0
. This and later versions of
Google Mobile Ads SDK
integrates with the
Open Measurement (OM) SDK
to enable third-party viewability measurement.
Google Mobile Ads SDK
supports OM SDK version 1.4.
Prerequisites
*
Google Mobile Ads SDK
7.43.0
or higher.
Implement Open Measurement
Google Mobile Ads SDK
automatically implements Open Measurement using
"Google" as the Open Measurement partner name for all ads served using the
Google Mobile Ads SDK
.
To use a third-party viewability provider, configure it in the
AdMob UI, and configure your line items to use that viewability
provider. For more details, see Configure a mobile app viewability provider.
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:
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 isHidden to TRUE.
Troubleshooting
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 overlaying views might not register viewability
measurements. For more information, refer to Ensure that transparent overlays
are non-obstructing.
On test devices, including the
iOS simulator, the Test Ad label is detected as non-obstructing
to the ad view.
