Identity Graph

An identity graph is a database that maps the many identifiers belonging to a single person, such as emails, device IDs, and cookies, into one connected profile. It is the data structure that makes identity resolution possible across channels and devices.

Each node in the graph represents an identifier; edges connect identifiers believed to belong to the same person. As new signals arrive, the graph links them to existing profiles or creates new ones.

Identity graphs power cross-device recognition, suppression, and audience building. The quality of a graph depends on the accuracy of its matching rules and the freshness of its underlying data.
