The First Step in Building a More User-Centric Internet
Where publishers control user privacy and their own data
Publishers can write the SharedID common identifier as a first-party value. SharedID stores a unique user ID, where the publisher can make the decision to either make this accessible to bidders, or use the user ID as a building block for publisher controlled first party self-declared data without the use of an identifier.
The Start of Something Cool
SharedID gives the advertising industry a place for independent ad tech and publishers to test, iterate and share proposals to fix the issues our industry currently faces. By creating a foundational layer of what we have today, and what we could use tomorrow, Prebid.org is currently working on further proposals that align with our organizations main goals of keeping publishers in control of their data, protecting user privacy and rebuilding a better internet.
Replace your proprietary value and use SharedID for sandboxing.
