Anonymous Visitor Identification

The Short Answer

Anonymous visitor identification is the specific process of resolving a website visitor who has not filled out any form or logged in to a verified identity, using signals like IP address, device data, and a consumer data graph. A meaningful share, roughly 25 to 40 percent, of verified human visitors can typically be identified this way, depending on the site and traffic source.

How It Works

Signals like IP address and device data are captured from an anonymous session, then matched against a consumer data graph using the same deterministic and probabilistic methods behind broader identity resolution.

Why It Matters

A meaningful share, roughly 25 to 40 percent, of verified human visitors can typically be identified this way, depending on the site and traffic source, turning otherwise invisible traffic into a workable audience.
