GA4 Implementation Audit

Is your GA4 data actually reliable? This audit identifies configuration errors, tracking gaps, consent issues and data quality problems so you can trust the numbers behind your marketing decisions.

Configuration review Checks the GA4 property setup, events, conversions, attribution and reporting settings.
Tracking validation Identifies missing, duplicate or inaccurate tracking that could distort your reporting.
Consent assessment Reviews whether analytics collection aligns with consent signals and privacy expectations.
Clear next steps Provides prioritised recommendations so you know what to fix first and why it matters.

Why a GA4 Audit Matters

GA4 is often used as the main source of marketing performance data, but it is easy for inaccurate tracking, poor configuration or consent issues to undermine trust in what the numbers are really showing.

This audit reviews your setup to identify data quality risks, tracking gaps and configuration problems, so you can understand whether your GA4 implementation is reliable enough to support reporting and decision-making.
