Active View measurement

The IMA SDK must be able to tell when ads are visible to users so that it can send the correct signals back to the ad server. IMA uses Active View reporting to measure the viewability of ads. This guide explains how Active View reporting works with IMA, as well as how to verify that the SDK is able to correctly capture viewability signals.

How Active View reporting works with the IMA SDK

  1. The publisher designates a container element when creating the AdDisplayContainer.

  2. As long as the AdDisplayContainer is viewable and unobstructed when the AdsRequest is made, Active View receives measurements on that container.

Verifying that the SDK can measure ad viewability

To check whether that the SDK is able to capture viewability signals, look for instances of active_view_vide_measurable_impression in the HTTP requests and check for the mtos parameter. For more information, see Monitor Active View measurement.
