The Challenge

  • •GTM container had accumulated 3 years of tracking tags with no documentation
  • •Same conversion was firing on page load, button click, AND thank-you page
  • •Cross-domain tracking was broken, causing sessions to split and conversions to multiply
  • •Client's internal team ran their own GA4 report and found the discrepancy
  • •Emergency call: "We need this fixed in 48 hours or we're being fired"

The Solution

Clean GTM architecture with documented tagging standards and verified conversion accuracy.

  • Documented every tag in the container and removed 19 deprecated/broken tags
  • Implemented proper trigger conditions with form_submit verification
  • Fixed cross-domain tracking with correct linker parameters
  • Added dataLayer push verification to prevent phantom conversions
  • Created GTM implementation SOP for all future client accounts
  • Set up monitoring alerts for conversion volume anomalies
"We were 48 hours from losing our biggest client. Conor not only fixed the immediate problem but gave us a system so this never happens again. We've since audited all our accounts and our reporting is bulletproof."
