Verify Active View

  • IMA SDK uses Active View reporting to measure ad viewability.

  • Active View receives measurements from the VideoAdPlayer instance passed to the AdDisplayContainer.

  • You can verify the SDK's ability to measure viewability by checking for network requests to https://pagead2.googlesyndication.com/pcs/activeview and the presence of the mtos parameter.

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 AdDisplayContainer is created by passing in an instance of VideoAdPlayer.

  2. Active View receives measurements on that VideoAdPlayer (getLocationOnScreen and getGlobalVisibleRect).

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.
