New GRP–Impressions Calculator with CIM Golden Standard 2026 Audiences

Retriever has launched a new GRP–Impressions calculator, developed in collaboration with CIM. The tool enables media professionals to instantly convert GRPs to impressions, and vice versa, based on CIM Golden Standard 2026 Audiences.

Through a direct API connection with CIM, Retriever always uses the most up-to-date official audience definitions. In addition to standard target groups, it is also possible to create combined audiences, making it possible to perform calculations for very specific target selections.

The calculator was developed to make media planning faster and simpler, while drawing directly on the reference audience data used in Belgium.

The new GRP–Impressions calculator is now available to users of the Retrievermedia.be database environment.
