Identity Resolution

Technical definition

The process of connecting multiple identifiers and data points to create a single, unified view of a customer across devices and touchpoints.

The ADLINGO translation

Connecting the person who visited your site on their phone, opened your email on their laptop, and bought something in your store into a single profile. The concept is simple. The execution involves device graphs, probabilistic matching, deterministic signals, and a lot of data infrastructure most brands underbuilt. The gap between "we have identity resolution" and "our identity resolution actually works" is wider than most teams admit.
