GRP (prospect) stands for Gross Rating Point prospect, and refers to a potential customer or client who has shown interest in a product or service through various marketing efforts. This term is commonly used in advertising and media industries to measure the reach and effectiveness of a campaign in attracting potential customers. A GRP prospect is someone who has not yet made a purchase, but has the potential to do so based on their level of interest and engagement with the brand. Identifying and targeting GRP prospects is crucial for businesses to convert them into loyal customers and increase their sales.
