What We Check

  • GTM container detection and version check
  • Tag firing analysis (which tags load on page)
  • DataLayer initialization verification
  • DataLayer.push() frequency analysis
  • Duplicate tag detection (gtag.js + GTM overlap)
  • Container size and load time impact
  • Tag naming convention review
  • Trigger configuration audit

Common Issues We Find

  • Duplicate GA4 tags firing (inflating page views)
  • Tags firing before consent is granted
  • No naming convention (impossible to manage at scale)
  • Abandoned tags from old campaigns still loading
  • Missing dataLayer initialization before GTM snippet

Why This Matters

A bloated or misconfigured GTM container slows your site, fires tags incorrectly, and can cause data discrepancies. Regular audits prevent tracking drift as your team adds new tags.
