Google Analytics

Definition

Google Analytics is Google's free web and app analytics platform that tracks visitor traffic, behavior, and conversions using an embedded tracking tag, with the current version, Google Analytics 4 (GA4), built around event-based data collection.

Overview

Google Analytics is the dominant web analytics platform, used by millions of sites to measure traffic sources, user behavior, and conversion performance. Site owners add a tracking snippet — often deployed through Google Tag Manager rather than pasted directly into page code — which sends event data to Google's servers as visitors browse the site or use a connected app. The current generation, GA4, replaced the older Universal Analytics model with an event-based data schema: essentially every interaction, from a pageview to a button click to a purchase, is modeled as an event with parameters, rather than the older session/pageview-centric model. This makes GA4 more flexible for tracking behavior across both websites and mobile apps in a unified property, and it integrates machine-learning-driven insights such as predictive audiences and anomaly detection. Google Analytics integrates tightly with other Google marketing and advertising products — Google Ads for campaign attribution, Google Search Console for organic search data, and BigQuery for raw data export and custom analysis. Because it's free at the standard tier and deeply integrated into the broader Google ecosystem, it remains a default choice for many businesses, though it has drawn scrutiny over data privacy and, in some jurisdictions, regulatory restrictions tied to GDPR-style consent requirements.
