Viewability

Viewability, powered by Pixalate, lets you know how many of the impressions that you won were viewable (appeared on the screen). Viewability information appears in your campaign delivery/performance reports, and you can manually optimize for domains, placements, and exchanges that are meeting your viewability goals. You can also use machine learning to optimize your campaign for viewability goals.

The option to turn on viewability is found in the General tab of the campaign editor.

When your campaign measures viewability, you'll have access to the metrics listed above, displayed along with the other campaign statistics and domain statistics:

  • Total eligible impressions: impressions against which Basis DSP can measure viewability.

    Currently, only desktop web and mobile web can be eligible impressions. We cannot measure viewability on video or mobile app impressions.

    If your campaign wins 1000 impressions, the eligible impressions must be equal to or less than 1000.

  • Total measured impressions: impressions for which Pixalate's script was able to determine viewability.

    If your campaign has 500 eligible impressions and 5 of those could not be determined, the total measured impressions would be 495.

  • Total viewable impressions: impressions which the script was able to deem viewable.

    If your campaign has 495 measured impressions and 85 of them were not viewable, the campaign has 410 viewable impressions.

  • Measured rate: (total measured impressions / total eligible impressions), as a percentage.

    If the campaign has 495 total measured impressions and 500 eligible impressions, the measured rate is 495/500 = 99%.

  • Viewable rate: (total viewable impressions / total measured impressions), as a percentage.

    If the campaign has 410 total viewable impressions and 500 measured impressions, the viewable rate is 410/495 = 82.83%.

Notes:
  • Pixalate viewability can be used with or without pre-bid viewability solutions through other data partners.

  • Viewability is only measured for display inventory (desktop and mobile).

  • Viewability for video inventory is not available at the moment.

  • If you use machine learning to optimize for viewability goals, viewability automatically turns on, and you cannot disable it. See Machine Learning Optimization for more information.
