Data Management Platform (DMP)

GLOSSARY

Definition

A data management platform collects and organizes audience data — mostly anonymous, cookie-based identifiers — for use in programmatic advertising. Advertisers use DMPs to build audience segments and push them to demand-side platforms for ad targeting.

Why it matters

DMPs were essential infrastructure for programmatic advertising from roughly 2012 to 2022. Then third-party cookies started dying. Chrome's Privacy Sandbox, Safari's ITP, and Firefox's ETP all eroded the cookie-based identifiers that DMPs depended on. Most DMP vendors pivoted to 'audience platforms' or got absorbed into CDPs. If you're evaluating a DMP today, ask what happens to your segments when cookies are fully gone.
