GA4 & GTM tracking audit before bad data costs you
If you are running paid ads or relying on GA4 to make decisions, broken tracking is one of the most common - and most expensive - problems agencies and small businesses never catch.
Duplicate events, missing conversions, and misconfigured cross-domain tracking can quietly skew your numbers for months. I will go through your setup, find what is broken, and hand you a clear, prioritised report on what to fix.
Signs your tracking might be broken
If any of these sound familiar, there is a good chance something is misconfigured.
- Conversion numbers in GA4 do not match what your ad platform reports
- Page views or events look duplicated or inflated
- Numbers changed suddenly after a site migration, redesign, or CMS switch
- You are not sure if cross-domain or subdomain tracking is even working
- Nobody currently in your team can confidently explain your GTM container
- E-commerce or lead conversion values look off
What's included in the audit

After the audit
Most issues found in an audit are quick to fix. If you would like me to implement the fixes directly, that is quoted separately based on scope - typically a fixed price agreed after you have seen the report, so there are no surprises.
Common follow-on work
- GTM container rebuild or cleanup
- GA4 event and conversion setup
- Cross-domain tracking implementation
- Server-side tagging
- Ad platform conversion integration (Google Ads, Meta CAPI)
Who this is for
Agencies
Who want a second pair of eyes on a client's tracking, or do not have in-house analytics depth - audits can be white-labelled if needed.
Small businesses running paid ads
Who are not confident their numbers are accurate.
Recent platform migrations
CMS change, replatform, or rebrand where tracking has not been verified since launch.
Background
I handle analytics and attribution for a portfolio of production websites, including cross-domain tracking and attribution setups for ticketing and e-commerce clients - the kind of tracking that has to be right, because ad spend and reporting decisions depend on it.
