Tracking you can trust: GA4, GTM and ad platforms that agree
When GA4, the ad platforms and the CRM show three different totals, every budget decision is a guess. We audit the setup, rebuild what is broken and leave you with one version of the numbers, in your own accounts.
Starts with a free audit: SEO, ad account or analytics (GA4, GTM). You keep the findings.
Why the numbers stop matching
You can't trust the numbers
GA4, the ad platforms and the CRM show three different totals, and every meeting starts with an argument about which one is right.
You can't see which campaigns bring customers
Platforms count clicks and form fills. Which campaigns produce paying customers and revenue stays a guess.
Tracking breaks and nobody notices
A consent banner, a site release, iOS or a booking engine quietly drops conversions, and the ad platforms keep optimising on the gap.
What you get
- A GTM audit and rebuild, web and server-side
- Consent Mode v2, with tag behaviour documented for each consent state
- Server-side tracking, Meta Conversions API and enhanced conversions, deduplicated
- GA4 to BigQuery, with modelled tables in Dataform
- Attribution joined to your sales or CRM data, with ad spend reconciled against real revenue
- Alerts for missing or broken data
- Documentation, and a weekly report you can defend
What stays in your hands
- Everything is built in your own GTM, GA4 and BigQuery accounts
- Read access is enough for the audit; nothing is published without your approval
- Tag behaviour is documented for each consent state
- Access is granted per account and can be revoked at any time
- The setup and its documentation stay with you if we stop working together
- A senior analytics specialist owns the account and decides what changes
Where we've done it
Our own site runs the same setup: Consent Mode v2, server-side GTM on a first-party domain, and GA4 exported to BigQuery.
AI agents audited and rebuilt measurement across GTM, GA4 and BigQuery: 40+ assets deployed under a human-approval gate, the full 9-step booking funnel instrumented, 3 mis-mapped steps caught before they corrupted the data.
Sales and marketing data unified into one governed warehouse: 3-layer attribution down to click level and all ad spend reconciled against real sales, with incremental models cutting analytics costs by ~96%. The SEO operation now runs AI-first: agents connected to Ahrefs over MCP do the recurring analysis and monitoring.
Advanced web analytics with cross-channel tracking, SEO strategy, digital marketing mix, A/B testing of the application funnel, and real-time dashboards. 70% of tracked search queries reached Google's top 3, and the Google Ads conversion rate rose to 5%.
How it starts
We review your GA4, GTM and consent setup and list what is broken, what is missing and what to fix first. You keep the findings either way.
A fixed scope: one agent, one workflow, one account or one tracking rebuild. You see every proposal before anything goes live.
We run and improve it: agents work daily, the specialist decides, and you get a live report on your own data.
Questions we get asked
Do you need admin access to start?
No. Read access is enough for the audit. Changes are prepared in a workspace and you approve them before anything is published.
Does it work with a consent banner and server-side tracking?
Yes. We set up Consent Mode v2 and server-side GTM for clients, and our own site runs the same setup.
Who does the work?
A senior analytics specialist owns the account. Agents run the audit checks and the monitoring; the specialist decides what changes.
What does it cost?
We quote after the free audit, once the scope is clear. You keep the audit findings either way.
