This mandate serves as a strategic roadmap for the media buying agency, providing them with clear guidelines and parameters to follow in order to effectively reach the target audience and achieve the desired results. It also ensures transparency and accountability between the client and the agency, as well as streamlining the media buying process for maximum efficiency and effectiveness.
