Video ads

Here is an example of a video ad:

  • only start and continue to play if in-view (on screen)
  • if user clicks to another tab or window, the video stops
  • charged on a Viewable Cost Per Mille (vCPM) basis – cost per 1,000 viewable impressions
  • a paid video impression is only counted if the ad has been 50% in-view for 2 seconds.
  • launch a campaign through our self-serve platform, MyDianomi, or your account manager
