Google Analytics 4 (GA4) is a complete rebuild from Universal Analytics - and yes, the learning curve is real. But once you understand how it works, it's incredibly powerful for understanding your audience and measuring ROI.
GA4 is now the only official Google Analytics platform. It tracks both websites and apps in one property, uses an event-based model, and is built for privacy-first, cookieless measurement.
In GA4, everything is an event. Page views, button clicks, video plays - all events. This makes GA4 far more flexible and precise than UA ever was.
Auto-collected events (page_view, session_start, first_visit) work out of the box. Custom events like form submissions require Google Tag Manager setup.Create GA4 property at analytics.google.com
