adcp

The Ad Context Protocol (ADCP) project provides documentation and a reference implementation for a standardized way to share contextual information about ad placements (like page content or user signals) between publishers and ad tech platforms. It is designed for publishers, ad servers, and advertisers seeking a privacy-conscious, interoperable alternative to third-party cookies for targeting and measurement. Its interest lies in enabling richer ad decisioning without relying on user-level tracking, aligning with evolving privacy regulations and browser restrictions.
