Verify Active View

  • The IMA SDK leverages Active View reporting to determine and relay ad visibility to the ad server, ensuring accurate measurements for billing and performance analysis.

  • Active View relies on the AdDisplayContainer and VideoAdPlayer components to gather spatial information about the ad's position on the screen.

  • Ad viewability can be confirmed by monitoring HTTP requests for active_view_vide_measurable_impression instances and the presence of the mtos parameter, signaling successful measurement.

  • If custom video displays are used, adjustments to the layout might be needed to guarantee proper metric collection and accurate Active View reporting.

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.
