Your campaign delivers 160.0 GRP - a solid media weight.

  • Your campaign sits in the 100-200 GRP range that many planners consider effective for awareness campaigns.
  • An average frequency of 4.0 sits in the effective 3-10 range where recall typically builds without fatigue.
  • Your Cost Per Point is $312.50, meaning you pay that amount for each 1% of audience weight delivered.
  • TRP of 100.0 shows the campaign weight delivered specifically against your target demographic.

Next stepTo improve efficiency, test whether increasing reach (broader media) or frequency (more spots) delivers better response for your category.
