What does a GRP of 80 indicate in advertising?

A GRP, or Gross Rating Point, is a standard measure in advertising that quantifies the total exposure of an advertisement across a specific audience. If a campaign achieves a GRP of 80, it signifies that the collective exposure of the advertisement amounts to 80% of the target audience multiplied by the number of times the advertisement was shown.

This means that the campaign has effectively reached a significant portion of the target demographics, leading to a substantial total impact. A GRP of 80 doesn't imply that 80% of the audience has seen the ad necessarily, as it involves the sum of ratings across all placements, which could include multiple viewings by the same individuals.

Likewise, claiming that 80 ad spots have been purchased does not relate to GRP, as this measure pertains to the reach and frequency of ads, not the quantity of inventory. Lastly, mentioning budget expenditure does not connect with GRP, which strictly
