About Google Analytics 4
Google Analytics 4 (GA4) is the free, industry-standard tool for understanding how visitors interact with your website and apps. It tracks sessions, traffic sources, user journeys, conversion events, and revenue — integrating natively with Google Ads, Search Console, and BigQuery. GA4's event-based model is more flexible than its predecessor Universal Analytics, enabling custom event tracking without code via Google Tag Manager. Despite its complexity, GA4 is non-negotiable for any serious website owner.
