What is GA4 Configuration Tag?

The GA4 Configuration Tag is a commonly used tag within Google Tag Manager that allows marketers to set up Google Analytics 4 tracking.

Core Benefits:

  • Auto pageview tracking - Tracks user views automatically
  • Event parameter setup - Sends custom data to GA4
  • Cookie control - Manages analytics cookies easily

Client-Side vs Server-Side:

Traditionally, the GA4 Configuration Tag runs client-side via JavaScript, which can be blocked by browsers and ad blockers. Server-side GTM provides better data reliability, security, and performance.
