Why would a media planner use GRP as a planning metric?

• A. To Assess Creative Quality and Tone.
• B. To Summarize Total Audience Exposure and Compare Plans Against Targets.
• C. To Calculate the Cost Per Impression.
• D. To Determine Optimal Ad Frequency Only for Social Media.

Answer: (B)

GRP, or Gross Rating Point, represents the total exposure opportunity for a target audience across a campaign. It’s the sum of all ratings across the schedule, which effectively reflects reach multiplied by frequency. Because it compresses how much exposure a plan is delivering into a single number, GRP lets you compare different media plans against your target exposure goals and see which one best meets the required audience reach and repetition. This metric is about exposure, not about the quality of the creative, and it doesn’t directly measure cost per impression. It also isn’t limited to social media—GRP is a broad planning metric used across channels.
