Delivery roadmap

How we deliver GA4 Data Quality Audit.

Step 01

Initial contact and scope definition

We start by understanding your setup and context: which properties to analyse, what business decisions the audit needs to inform, any known issues or concerns, and whether the GTM implementation should be in scope. This shapes everything that follows.

Step 02

Audit execution

We work on the audit based on the agreed scope, reviewing data quality, attribution issues, tracking setup, compliance signals, and any GTM-related elements included in scope.

Step 03

Audit delivery

We deliver the audit documentation with clear findings and practical next steps for each issue identified.

Step 04

Optional walkthrough call

If you want, we can schedule a call to go through the findings together, answer questions, and discuss implementation priorities.

GA4 Data Quality Audit scope and hours

  • You don't get generic advice copy/pasted from other audits.
