gross rating point (GRP)

Gross Rating Point (GRP) is a parameter for evaluating advertising, which originates from television advertising and can be used to compare advertising media.

The Gross Rating Point is the number of contacts in relation to a target group. Specifically, it is the net reach in percent multiplied by the average contacts. Since the reach can be related to a target group, the GRP value can be calculated from the quotient of the number of contacts and the absolute number of target persons in a target group.

For example, if 70% of a defined target group is reached and each target person has seen the advertisement four times, then the GRP value is calculated by multiplying 77% and 4, than the GRP value is 280.

This assessment can also be applied to online advertising.
