(01)what’s included

What we check in your GA4 audit.

We combine strategy, technology and data to improve your business results.

Property configuration

We review data streams, time zone, unwanted referrals, internal traffic and cross-domain measurement against how the website is actually used.

Events and conversions

We test forms, purchases and other key events. We check that parameters and values arrive, each action counts once and the event reflects a real action.

Google Tag Manager container

We inventory tags, variables and triggers. We identify duplicate code, fragile dependencies and differences between published versions and the measurement plan.

Google Ads and Meta pixels

We review firing, values and deduplication where browser and server events are combined. We compare advertising conversions with GA4 and explain differences.

Consent and attribution

We test acceptance, rejection and preference changes. We review campaign attribution retention and check for personal data in URLs and events.

Report and correction plan

You receive an issue inventory with evidence, priorities and recommendations. We distinguish configuration fixes from work requiring development or an integration.

(03)questions

Frequently asked questions

Does the audit include fixing GA4 errors?

The audit delivers a diagnosis and correction plan. Implementation is quoted separately or explicitly included in the proposal. Your team or ours can carry out the corrections.

What access do you need to audit Google Analytics?

We usually need read access to GA4 and the GTM container, plus access to platforms in scope. We agree on a test method for purchases or private areas. We do not need to publish changes to produce the diagnosis.

Why do Google Ads and GA4 report different conversions?

They can use different attribution windows, models, recording dates and counting rules. Consent and implementation issues also affect results. The audit separates expected differences from errors requiring correction.

Can you recover data that GA4 never recorded?

Fixing a tag does not rebuild history that was never collected. If orders or records exist in other sources, we can assess reconciliation for analysis while documenting their origin and limitations.

How much does a GA4 audit cost and how long does it take?

Pricing depends on the properties, containers, domains and journeys to test. Once scope and access are defined, we agree on a delivery date in writing. Installations with different levels of complexity require different scopes.
