Understanding GRP (Gross Rating Points)
What is GRP?
Gross Rating Point (GRP) is a standard metric used in advertising to measure the impact and effectiveness of television and radio ad campaigns. It combines reach and frequency to provide a single metric for campaign evaluation.
Key Components
- •Reach: Percentage of target audience exposed to the ad
- •Frequency: Average number of times each person sees the ad
- •GRP: Product of reach percentage and frequency
- •Impressions: Total number of ad exposures
GRP Calculation
Formula: GRP = Reach Percentage × Frequency × 100
Where:
- • Reach % = (Audience Reached ÷ Total Audience) × 100
- • Frequency = Average exposures per person reached
Note: GRP can exceed 100 when frequency is high, as it measures total exposure potential
