People are spending more time on their mobile phones, especially in apps, and move across screens frequently. As people's usage of mobile apps has grown, so has the importance of standardizing the way viewability is measured on mobile devices.

Today we're sharing how we've made in-app inventory more measurable through the IAB Tech Lab's Open Measurement standard. Integrating the Open Measurement Software Development Kit (SDK) into both our Google Mobile Ads (GMA) and Interactive Media Ads (IMA) SDKs has allowed us to enable Open Measurement on 85+ percent of in-app display and video impressions on Google AdMob and Google Ad Manager publishers. This means that buyers of this inventory can now take viewability measurements using solutions like Integral Ad Science, DoubleVerify, Comscore, and Moat in addition to measurement that was previously available with Active View.
