What We Check
- GTM container detection and version check

- 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.
