A finding earns its place in the plan only when someone else can reproduce it from the evidence.

A useful GA4 audit does more than list suspicious settings. We rank each finding by its effect on decisions, identify what can safely stay as it is, and give your team a sequence it can start executing the same week. You end up with a ranked GA4 remediation plan with evidence, ownership, and enough context for an engineer to pick it up directly.

We map the estate, test real journeys, reconcile important totals, and rank findings by decision impact. Five steps move from a defined estate and baseline to an owned remediation plan.

How we hold ourselves to it

Everything connected to the property, mapped and owned — We inventory every property, stream, linked account, and integration, then record its owner and whether it is still needed.
Where signup, purchase, or lead flows actually break — We test signup, purchase, or lead journeys and compare what GA4 records with what each journey should produce.
How far GA4 drifts from the numbers you trust — We reconcile GA4 totals against trusted order, lead, or subscription records to locate and quantify the gaps.
Findings ranked by cost rather than by ease of the fix — A broken event on the homepage does not carry the same weight as one on an abandoned test page. We prioritize decision impact rather than ease of repair.

Scope the estate
We inventory the properties, streams, containers, and integrations, then agree on the audit boundary before testing begins. The team confirms which assets are actually in scope.
Asset inventory
Set the baseline
We identify the important numbers and agree which system is the source of truth for each. The stakeholder picks the number GA4 must match.
Baseline agreement
Test real journeys
We test the journeys your business depends on, recording what fires, what is missing, and what fires twice. The analyst confirms a flagged event is a real defect.
Journey test log
Reconcile and rank
We compare GA4 with trusted sources and rank each finding by its effect on a decision your team makes. The analyst ranks findings by business impact over ease.
Ranked findings register
Hand over the plan
We hand over the sequence, assign an owner to each fix, and document the checks required before release. Engineering lead confirms who owns each fix.

We complete four passes over the property before writing recommendations.

Automation pulls the property and stream lists, flags events that fire twice or not at all, and calculates the variance between GA4 and your trusted totals. Every verdict is human: what is in scope, which number GA4 must match, whether a flagged event is a real defect, and how findings rank once cost rather than ease decides the order.

Each deliverable includes the evidence and context another analyst or engineer needs to continue the work.

Prioritized backlog
Ranked remediation plan
Every fix in priority order, with the reasoning behind the ranking so it still makes sense if someone revisits it in six months.

We call it done when: every finding carries evidence a second analyst can replay, and every fix in the plan has a named owner.

This audit fits teams that need to understand whether the whole property can be trusted before fixing individual events.

A good fit when

You inherited a GA4 property from a past team, agency, or vendor and don't fully trust what it reports.
Several domains, apps, or markets feed one property and nobody has mapped what's actually connected.
Engineering will not commit time to the property until a defensible remediation plan shows which fixes come first and why.
GA4, GTM, and trusted order or lead totals are available, but nobody has reconciled them inside one audit boundary.

Better handled as other work when

You already trust GA4 and only need event names and key events cleaned up. That is GA4 Event & Conversion Tracking.
You're building a property from zero with no history to audit. That is GA4 Implementation & Configuration.
The real gap is measurement spread across many platforms rather than one GA4 property. That is Analytics Audit & Measurement Roadmap.

If one of these is closer to your situation, start here instead: All Google Analytics & GA4 Consulting tasks

We call it done when: the audit boundary is agreed and every number GA4 will be checked against has a named source of truth.

Zeo designs measurement systems that connect a business decision to governed collection and reporting you can check. The people shown here work on the part of that system this page covers.

Plan a GA4 audit

Will this touch our live GA4 or GTM setup?

No. Discovery is read-only. Anything we recommend changing gets scoped as its own piece of work, with its own release and rollback plan.

How is this different from just fixing our events?

If you already trust the shape of your GA4 property and only the event names and key events are messy, the narrower GA4 Event & Conversion Tracking task is a better fit. This audit is for cases where the whole property may be unsound, including its properties, streams, integrations, and events.

What if some historical numbers just won't match going forward?

Some breaks are real and permanent. A platform migration or an event redesign can create one without indicating a current defect. We explain which gaps are worth investigating and which comparisons should stop.

What do you need from us to start?

Read access to GA4 and GTM, the order, lead, or CRM numbers you already trust, and one person who can confirm what your business actions mean.
