What the Audit Found

  • GA4 tag not loading on 18% of pages due to conditional GTM trigger
  • Consent mode default state missing, causing 30% of EU traffic to send full data without consent
  • 5 custom dimensions registered but receiving no data for 3+ months
  • Self-referral traffic from their own subdomain inflating session counts by 12%

Data quality score improved from 38 to 86 within 3 weeks. Marketing team reduced reporting discrepancies by 94% and now runs automated weekly audits instead of manual quarterly reviews.
