Whether your objective is Reach, Engagement or Conversions, it's helpful to understand specific metrics related to your video. Here's a guide to what's measured for video.

To see video metrics in Ads Manager, click Columns > Video engagement. You can always change the data you see by customising your column view. For example, if you are seeing 3-second video views but want to see how many 10-second views you got, customise your column view for 10-second video views.
