Standard Media Index, in conjunction with agency and brand partners, makes it possible for the industry to have a real-world view into advertising spend by product category, ad revenue to media publishers and digital platforms, media pricing including CPMs, and future-booked commitments. SMI accesses actual spend from the world's largest media buying groups, as well as leading independents, and then organizes that data to create a clear, granular, and easy-to-use database for our clients and agency partners.
