About Google Analytics

Google Analytics (GA4) is the most popular web analytics service in the world, used by tens of millions of websites to track and report on user traffic, behavior, and conversions. The platform provides a complete understanding of the customer journey across websites and apps throughout their entire lifecycle, powered by Google's machine learning for predictive insights and privacy-safe modeling. GA4 offers real-time reporting, acquisition and engagement reports, monetization analytics, funnel explorations, path analysis, cohort analysis, and data-driven attribution modeling. The platform integrates deeply with Google's advertising ecosystem (Google Ads, Display & Video 360, Search Ads 360) and Google Cloud BigQuery for advanced data analysis. For enterprise needs, Analytics 360 adds continuous intraday data freshness, sub-properties, roll-up reporting, enhanced limits (125 custom dimensions, 400 audiences), and unsampled explorations for up to 50 billion events per day. Key limitations include a steep learning curve for GA4 compared to the legacy Universal Analytics, data sampling in the free tier for large datasets, and dependence on cookie consent which affects data accuracy in privacy-focused regions.
