GRPs (Gross Rating Points)

GRPs (Gross Rating Points) are an advertising industry metric used to measure the effectiveness of advertising campaigns.

GRPs measure the total number of contacts (or impressions) of an advertising campaign within a specific target group. They are usually calculated based on advertising campaigns such as TV commercials, radio ads or print ads and are based on the reach and frequency of the ads.

A GRP is calculated by multiplying the reach (percentage of the target audience that saw the ad at least once) by the average frequency with which that audience saw the ad.

GRPs can help evaluate and plan the success of an advertising campaign by giving an idea of how many people within the target group have seen an ad and how often they have seen it.

Example calculation Gross Rating Points:
 

To do an example calculation for GRP, let's assume that an advertising campaign for a new product has been launched and the goal is to address a target group of 18-49 year old women. The campaign should achieve a reach of 50% and a frequency of 3.

To calculate the GRP value, we multiply the reach (in percent) by the frequency:

GRP = Reach x Frequency

In this example, the reach is 50% and the frequency is 3:

GRP = 50 % x 3
GRP = 150

So the GRP value for this ad campaign is 150, which means that the average person in the target group has seen the ad 1.5 times (average frequency) if the ad was broadcast to half of the target group (reach of 50%).
