The essential differences
- Data model : Sessions (UA) vs Events (GA4)
- Flexibility: Easier personalized tracking in GA4
- Artificial intelligence : Predictive analysis integrated into GA4
- Privacy : GA4 designed for a world with fewer cookies

GA4 benefits
- Native cross-device tracking
- Easily customizable events
- AI for predictions and alerts
- Greater respect for privacy
Challenge GA4
- A new interface
- Different indicators (engagement vs. bounce)
- History non-transferable
- Learning curve
Integrated artificial intelligence
GA4 integrates automatic learning functions: trends highlighted, anomaly alerts, purchase behavior predictions. A step ahead for marketing managers.
Privacy and compliance
GA4 handles IP addresses differently, enables fine-tuning of personal data, and adapts better to the cookieless world. An asset for compliance RGPD.
Advice : Take the time to familiarize yourself with the new GA4 interface. Engagement rate replaces the classic bounce rate, and reports can be customized to suit your needs.
