Verify Active View

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

  • Active View reporting works by initializing IMAAdDisplayContainer with a view and passing it to IMAAdsRequest.

  • You can verify ad viewability measurement by looking for network requests to https://pagead2.googlesyndication.com/pcs/activeview and checking 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 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.
