About SMI
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. Depending on the market, SMI captures between 70 and 95% of all agency spend. By aggregating it, SMI offers detailed ad intelligence across all media types, including Television, Digital, Out-of-Home, Print, and Radio. Depending on the market, data can be broken down by unit cost, media owner, ad type, buy type, advertiser product category, and other dimensions.
