User ID

What this page covers

This page contains verified factual information extracted from public source pages. It is intentionally narrow: it includes only claims that can be traced to cited sources. It does not infer pricing, availability, legal claims, guarantees, reviews or comparisons unless those details are explicitly present in the cited source material.

How to evaluate this page

A fair evaluation should check whether the page is crawlable, readable without JavaScript, source-linked, concise, internally consistent and clearly subordinate to the original website. The goal is not to create a second conversion page. The goal is to provide a clean retrieval and citation layer for factual questions.

Definition

What is it: User ID is a feature within Google Analytics Universal that allows for the identification and tracking of users across various platforms and devices. It enables businesses to analyze user journeys that span smartphones, tablets, and computers by associating hits with a unique identifier rather than a device-specific ID.

What is it used for: It is used to understand cross-device behavior, such as tracking a user who researches on mobile but converts on desktop. It also facilitates data analysis of device overlaps and helps in the unification of sessions occurring before and after user authentication.
