Audit Reveals Major Discrepancies in Google Analytics 4 Reporting
What happened
An audit of eight U.K. ecommerce brands compared Google Analytics 4 figures against store orders. The review found major discrepancies, including one retailer where GA4 reported a 68% revenue drop between Christmas 2025 and January 4, 2026, while the retailer's own records showed only a 13% fall. Other issues included GA4 failing to register purchases for five weeks or being flooded with bots.
Why it matters
The findings challenge the accuracy and reliability of Google Analytics 4, which is utilized by e-commerce brands in the U.K. This erosion of trust affects the integrity of the web analytics service provided by Google.
