Google Analytics 4 (GA4) provides comprehensive insights into user behavior through four key stages: Acquisition, Engagement, Monetization, and Retention. The platform uses dimensions (qualitative attributes like campaign source) and metrics (quantitative values like active users) to structure reports. Key reports include general overview for KPIs, acquisition for traffic sources, engagement for user interactions, monetization for revenue tracking, and retention for user loyalty analysis. The Google Analytics Data API enables programmatic data export using Python, requiring Google Cloud Console setup with service account credentials and property ID configuration. While the API offers powerful automation capabilities, users should be aware of potential data discrepancies and sampling limitations compared to the GA4 interface.
