What are the advantages of the Google Analytics 4 tag?

Google Analytics 4 uses event-based measurement. The module sends supported store interactions so that you can analyze them in your GA4 property.

• Ecommerce events help you examine product views, carts and purchases. See the events supported by the module.
• GA4 reports and explorations help you investigate journeys and performance. Events that matter to your business can be used as key events.
• The User-ID feature can help connect interactions from the same signed-in customer across devices.
• Automated insights and modeling are Google Analytics features. Consent-related modeling depends on data volume, data quality and eligibility requirements; it does not automatically recover every unobserved action.
• Linking Google Ads and using other Google features require their own configuration. Stream enhanced measurement does not replace the module’s specific ecommerce events.

GA4 still has collection and configuration limits, including limits on parameters and some value lengths. Choosing GA4 or a consent banner alone does not guarantee exhaustive collection, business results or compliance for your entire website.
