What we check
The same areas every time, weighted towards whatever is most likely to be costing you.
Conversions
Are the right actions counted, once, with values? Do they match real enquiries and orders?
Ad platform tags
Google Ads, Meta, Microsoft and others: firing on the right events, with the right data.
GA4 configuration
Data streams, key events, filters, cross-domain settings and data retention.
Tag Manager container
Duplicate, orphaned and misfiring tags, triggers that fire too early, naming and versions.
Consent
Your cookie banner, Consent Mode and whether tags respect the choice people make.
Ecommerce data
Purchases, revenue, refunds and product data, checked against your platform.
Attribution and sources
Unassigned and direct traffic, broken UTMs, self-referrals and lost click IDs.
Server-side and APIs
Server containers, conversion APIs and deduplication between browser and server events.
Reporting
Whether the dashboards people rely on show what they think they show.
Health check or full audit?
Health check
An hour in your setup before we speak, then a 45-minute call on the biggest problems, in order of how much they matter.
- Best when something looks off and you want to know what
- Single site, a handful of conversions
- Talked through on the call
Full audit
Every tag, event, conversion and consent setting, written up as a prioritised fix list that a developer or agency can work from.
- Best for ecommerce, several platforms or several domains
- Useful before a migration, a relaunch or a new agency
- Written up, with a walkthrough call

Tracking audit questions
What's the difference between the health check and the full audit?
The £75 health check is one hour in your GA4, GTM and ad platforms followed by a 45-minute call: the biggest problems, in order, talked through. The £337 full audit is five hours covering every tag, event, conversion and consent setting, written up as a prioritised fix list you can hand to anyone.
What access do you need?
Read access to GA4, Google Tag Manager and the ad platforms you use (Google Ads, Meta, Microsoft and so on). Access to your consent tool helps. Nothing gets changed during an audit.
Can you fix what you find?
Yes, if you'd like us to. Fixes are billed at the same hourly rate, small ones in 30-minute increments. Or take the list to your developer or agency: the findings are yours.
Why don't GA4 and Google Ads ever match exactly?
They measure differently: different attribution, different time zones, different handling of consent and cross-device journeys. Some gap is normal. A big or growing gap usually means something is broken, and the audit will tell you which.
Do you audit server-side setups?
Yes. Server-side GTM containers, hosting, conversion APIs and deduplication between browser and server events.
