Definition
Google Analytics is Google’s analytics service for websites and apps, used to understand traffic sources, user behavior, and conversions. Officially it is positioned as a tool to “get a complete understanding of your customers across devices and platforms”, with the tools offered “free of charge” and a paid enterprise tier, Analytics 360, alongside the standard version. See the official page.
How it works
After a tracking tag is deployed on a site or app (it can be paired with Google Tag Manager), data accumulates in one property, and reports cover the customer journey across sites and apps throughout its lifecycle. The official page lists integrations with Google Ads, Search Ads 360, Display & Video 360, Google Cloud, and Search Console, plus insights powered by Google’s machine learning. The current version is Google Analytics 4 (GA4): per the official support page, standard Universal Analytics properties stopped processing data on July 1, 2023, and GA4 “has replaced Universal Analytics”.
Usage
It fits site and app owners measuring traffic, behavior, and marketing conversions — especially teams advertising on Google who need attribution and cross-platform reporting. Personal sites can also use it to observe where visits come from.
Related and confusable terms
GA4 and Universal Analytics are successive generations, and the older one no longer processes data; the free standard tier and Analytics 360 are two commercial tiers of the same service. Google Analytics is hosted by Google, which distinguishes it from self-hostable open-source analytics such as Umami, covered on this site.
Episode discussion
In Weekly #007, in the chapter “Agent 流量、个人网站与开放接口” (Chinese transcript), Xiangyang Qiaomu points out that existing web analytics lack tracking for AI training crawlers and personal-agent fetches, and Yang Pan replies “just build a new-era Google Analytics”. This is a speaker using Google Analytics as shorthand for traditional web analytics, not a description of the product. See the chapter.
