What is GA4?
Google Analytics 4 – Google's latest analytics platform for measuring website and app activity.
Understanding GA4
GA4, or Google Analytics 4, is Google's newest analytics platform that replaced Universal Analytics in 2023. GA4 uses an event-based data model instead of session-based, providing more flexibility and better cross-device tracking.
GA4 was built for a privacy-first world with cookie restrictions and GDPR requirements. It uses machine learning to fill data gaps and predict user behavior. Key features include enhanced e-commerce tracking, cross-platform measurement (web + app), improved funnel analysis, and built-in BigQuery integration. The interface and reporting structure differ significantly from Universal Analytics, requiring teams to adapt their analysis workflows.

GA4, or Google Analytics 4, is Google's newest analytics platform that replaced Universal Analytics in 2023. GA4 uses an event-based data model instead of session-based, providing more flexibility and better cross-device tracking.
What does GA4 stand for?
Why is GA4 important?
GA4 is now the standard for web analytics, and Universal Analytics data is no longer being collected. Its event-based architecture provides much more flexibility for tracking custom user interactions than the old session-based model. The machine learning capabilities help fill gaps from cookie restrictions, though this also means data is increasingly modeled rather than observed—understanding these limitations is crucial for accurate reporting.
