Frequently Asked Questions
Can GRP be over 100?
Yes! Since it multiplies reach by frequency, GRPs often exceed 100. 200 GRPs means the average person saw the ad 2 times (if reach was 100%) or 4 times (if reach was 50%).
Difference between GRP and TRP?
GRP measures total audience exposure. TRP (Target Rating Points) measures exposure specifically within your target demographic.
