Verify Active View

  • The IMA SDK uses Active View reporting to measure ad viewability, ensuring ads are visible to users before sending signals to the ad server.

  • Publishers initialize the process by linking their ad display container and ad request, enabling Active View to measure the view.

  • Viewability can be verified by monitoring HTTP requests for active_view_vide_measurable_impression and the mtos parameter.

  • Custom video display implementations may require layout adjustments to ensure accurate viewability metrics, with support available through the IMA support forum.

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 initializes the IMAAdDisplayContainer with a view.

  2. The publisher passes the IMAAdDisplayContainer to the IMAAdsRequest constructor.

  3. Active View receives measurements on the view.

Verifying that the SDK can measure ad viewability

To check whether that the SDK is able to capture viewability signals, look for network requests sent to https://pagead2.googlesyndication.com/pcs/activeview and check for the mtos parameter. For more information, see Monitor Active View measurement.
