Case Studies

Real results from real properties. Here is how three different organizations used GA4 Audits to transform their data quality.

Case Study #1

Mid-Market SaaS Platform

Industry: B2B Software

Size: 200-500 employees

38

Before

86

After

The Problem

Marketing team suspected GA4 data quality issues after noticing inconsistencies between GA4 reports and internal database metrics. Manual auditing was taking 2 weeks per quarter and still missing issues.

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%

Impact

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.

Case Study #2

DTC E-commerce Brand

Industry: Retail / E-commerce

Size: 50-200 employees

44

Before

91

The Problem

CFO flagged that GA4 reported revenue was consistently 15-20% higher than actual Shopify revenue. The analytics team could not identify the source of the discrepancy.

What the Audit Found

  • Duplicate purchase events firing on order confirmation page reload
  • Missing currency parameter on 40% of purchase events, defaulting to wrong currency
  • Add-to-cart events not firing on mobile product pages (responsive template issue)
  • BigQuery export data lagging 48+ hours behind the GA4 interface

Impact

Eliminated $23,000/month in phantom revenue from duplicate transactions. Fixed mobile tracking gap that was hiding 35% of add-to-cart behavior. Revenue accuracy improved to within 1.2% of Shopify data.

Industry: Professional Services

Size: 10-50 employees

52

84

  • 23 properties had UTM parameter inconsistencies fragmenting channel reports
  • 8 properties had consent mode implemented but not functioning correctly
