Measuring viewability accurately and at scale for mobile in-app has presented significant challenges — until now. You deserve the same level of data that you’ve come to expect in web environments. We were the first to use the MRAID standard as a way to offer mobile in-app viewability measurement at scale. As this method has limited metrics, we developed and are accredited for an open-source verification SDK (software development kit), that is now under the governance of the IAB Tech Lab. Open sourcing the code provides multiple benefits — independent, trusted verification at scale, eliminating operational inefficiencies introduced by multiple SDKs or limited insights from MRAID-based alternatives.
