How Themerella detects Google Analytics 4

  • gtag config calls for GA4 properties
  • googletagmanager.com/gtag/js resources with a G- id

Every detected technology should include category, confidence, evidence, and practical risk/context so the result is useful beyond logo recognition.

False-positive boundary

What to verify before acting on Google Analytics 4 evidence

  • Google Tag Manager can load GA4 without obvious page HTML markers.
  • Consent mode or server-side tagging can hide client-side GA4 evidence.
Next workflow
  • Confirm GA4 evidence from scripts and metadata.
  • Check whether consent, performance, and privacy findings affect analytics quality.
  • Use monitor workflows to catch tracking removal or tag drift.
