Google Analytics 4
Google Analytics 4 (GA4) is a web and app analytics platform developed by Google that tracks and reports website and application traffic and user behavior. It uses an event-based data model instead of session-based tracking, allowing for more flexible and detailed analysis across platforms. GA4 integrates machine learning for predictive insights and focuses on user privacy with features like cookieless measurement.
Developers should learn GA4 when building or maintaining websites or mobile apps that require data-driven decision-making, as it provides insights into user engagement, conversion tracking, and audience segmentation. It is essential for e-commerce, marketing, and content platforms to optimize user experience and measure campaign effectiveness. GA4 is particularly valuable for cross-platform applications due to its unified tracking across web and mobile.
