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.
The publisher passes the IMAAdDisplayContainer to the
IMAAdsRequest
constructor.
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
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.
The following sample stream is available for viewability testing:
CMS ID: "2556080", video ID: "tears-of-steel-omid"
To test using this stream, first check the network logs for
ima-test-verification.js to be downloaded and then a ping fired to
https://pagead2.googlesyndication.com/pagead/gen_204 at the start of ad
playback.
