Bridging the Gap Between Traditional and Digital

Multichannel media plans are often built using GRPs and TRPs to connect both linear and digital advertising, allowing planners to create one cohesive plan. Using a standard form of measurement across traditional and digital buys allow advertisers to compare the value of traditional mediums to different online channels, such as programmatic video, advanced TV and digital audio. An impression calculator can help you convert GRPs to impressions to use on a multichannel media plan.

Best Practices

  • Utilize GRPs and TRPs for extensions to your traditional buys.
  • Make sure to combine your GRP and TRP goals with your reach and frequency goals.
