Configure a mobile app viewability provider

Measure viewability with Ad Manager & the Open Measurement SDK

Some video features may not be enabled for your network. Contact your account manager for information.

Open Measurement provides secure cross-publisher mobile app viewability measurement for supported third-party viewability providers. Based on an industry standard, app developers can allow viewability measurement by any supported vendor with just one SDK integration. Once integrated, publishers can assign a viewability provider to an Ad Manager line item.

Ad Manager currently supports the following viewability vendors:

  • Moat 
  • Integral Ad Science (IAS) 
  • Comscore 
  • DoubleVerify 

SDK implementation

There are two SDKs that integrate Open Measurement. 

For simple video implementations, developers should refer to the Google Mobile Ads (GMA) SDK for information about how to import the SDK with Open Measurement capabilities, and enable Open Measurement. Guides are available for either iOS or Android.

For advanced video capabilities, developers should refer to the Interactive Media Ads (IMA) SDK for information on how to import the SDK with Open Measurement capabilities, and enable Open Measurement. 

Complete information on the Open Measurement standard can be found in the IAB documentation.

Configure a viewability provider for your Ad Manager network

Third-party viewability providers must be added to your Ad Manager network before they are available to assign to your line items. Learn how to add a new company.

What you'll need to add a viewability provider

You should obtain the following from each provider that you wish to add to your Ad Manager network. Additional settings, like contact information for the vendor are optional.

Vendor key

The vendor key usually has the format of [domain]-[usecase].


Script URL The URL that hosts the verification script for the vendor.
URL parameters The parameters that should be passed to the downloaded verification script. These are the same as the VerificationParameters in the VAST 4.1 spec.
Rejection tracker URL The URL that should be pinged if the verification script cannot be run.

Assign a viewability provider to a line item

Once a supported viewability provider has been successfully added to your Ad Manager network, you can assign it to your line item and begin allowing third-party viewability measurement for creatives assigned to that line item.

Only one provider can be added per line item.
