Nielsen Digital Ad Ratings provides a comprehensive, next-day view of your ad performance in a way comparable to Nielsen TV ratings. In the context of a Roku channel, Nielsen DAR provides additional value to your RAF video advertisements and may increase your advertising revenue. If you are not a Nielsen DAR customer, you may not receive reports on DAR campaigns.

The Roku implementation of Nielsen DAR embeds information about the specific video item, such as genre, name, and runtime, into the VAST requests for video ads in your channel. In addition to the genre settings, Nielsen DAR requires an accurate Title parameter and Length parameter for each video in order to function correctly. When using Nielsen DAR the Title parameter for each video should consistently reflect the program (movie title or series name), and should not uniquely identity episodic content.

    "The Price is Right"
    "Leave It To Beaver"
    "Police Academy 7: Mission to Moscow"

To enable Nielsen DAR in your Roku channel please perform the following steps:

  1. Set the Theme RAFNielsenEnabled parameter to "True".
  2. If Nielsen has provided you with your own App ID, enter it into the Theme RAFNielsenAppId parameter, otherwise use the default Roku App ID "P2871BBFF-1A28-44AA-AF68-C7DE4B148C32".
  3. The Theme RAFGenreMacroSource parameter should be set to "Ad Genre Tags" or "Categories".
    • If set to "Ad Genre Tags" then each ad must specify a valid Roku genre in its Tags parameter.
    • If set to "Categories" then each video item must specify a valid Roku genre in its Categories parameter.
