Google Analytics 4 is free for standard use with no traffic limits on data collection. The paid tier, GA4 360, starts at approximately $50,000 per year and adds higher data limits, BigQuery export quotas, enterprise support, and uptime guarantees.

GA4 360 adds higher data processing limits, longer data retention (up to 50 months vs. 14 months), enterprise-level support, uptime SLAs, and expanded BigQuery export quotas. The core reporting and event-tracking features are identical. Our data shows most GA4 users are 1-10 employee companies, suggesting the free tier meets the majority's needs.

Yes. GA4 replaced Universal Analytics (UA) in July 2023. GA4 uses event-based data collection instead of session-based, tracks both websites and apps in one property, and relies on machine learning for predictive metrics. Our data shows 53,179 companies migrated from Universal Analytics to GA4, with the bulk of transitions happening in 2023.

Privacy concerns drive most departures. GA4 sends user data to Google's servers, which conflicts with GDPR requirements in some EU interpretations. Ad blockers also reduce GA4's accuracy. Our migration data shows 9,587 companies moved from GA4 to Site Kit and 28,438 to Facebook Pixel, suggesting some prefer simpler or more privacy-focused alternatives.

GA4 uses three identity methods: User-ID (for logged-in users), Google Signals (for users signed into Google accounts), and device-based modeling. This lets GA4 stitch sessions across phones, tablets, and desktops. Our data shows 98.71% of GA4 sites are mobile-compatible, indicating cross-device tracking matters for the vast majority of users.

TechnologyChecker.io tracks 3,688,199 active domains running GA4 as of March 2026. An additional 2,981,588 domains have previously used GA4 but no longer carry the tag. GA4 ranks #3 in the web analytics category with 14.95% market share, though combined with other Google tags, Google controls over 61% of web analytics detections.

GA4's GDPR compliance is debated. It offers IP anonymization, consent mode, data retention controls, and server-side tagging options. Some EU data protection authorities have ruled standard GA4 implementations non-compliant because data is transferred to US servers. Companies in Europe often use consent management platforms alongside GA4 to meet requirements.
