## Gross Rating Point

Gross Rating Point (GRP) is a metric used to measure the effectiveness of an advertising campaign. It measures the impact of an advertisement in a particular market based on the percentage of the population that was exposed to it. GRP is calculated by multiplying the total number of impressions (or number of times an advertisement is seen) by the target audience’s average rating. This allows marketers to measure the reach of an advertisement and compare it with the target audience size. To understand GRP, it is important to understand the following related terms:

**Impressions:**The number of times an advertisement was seen by its target audience.**Average Rating:**The average rating of the target audience for the advertisement.**Reach:**The percentage of the target audience that has seen the advertisement.

GRP is a useful tool for marketers to understand the impact of an advertisement on its target audience. By measuring the number of impressions, average rating, and reach, marketers can get an accurate picture of how successful their campaigns are. For example, if an advertisement has 500 impressions and a reach of 50%, it would have a GRP of 250. This means that the advertisement was seen by 250 people in the target audience. GRP is an important metric for marketers to understand the effectiveness of their campaigns and make sure they are reaching the right people.
