Google Analytics is only as good as the data you feed it.

Without a full, correct implementation, you see only a fraction of the story on user behaviour and performance. Our analytics audits make sure your data is recorded accurately, so you can make better business decisions, and our consultancy helps you uncover the real insights it holds.

We have helped hundreds of local, national and international brands extract and visualise the data they need, across Universal Analytics, GA4 and 360, so we have a keen eye for what matters and what to fix first.

What we audit
Tracking implementationThe status of your tracking: is it capturing the user behaviour and performance metrics that matter.
Admin & configurationYour GA4 admin settings, conversions and definitions, checked for correctness and completeness.
Setup debuggingIdentifying and documenting implementation errors, with clear resolutions to put them right.
Tag manager auditHow your data is tracked through GTM, so tags fire correctly and do not conflict or duplicate.
Performance analysisThe layer underneath: interpreting the data so the audit ends in insight, not just a fix list.

Five reasons analytics audits matter more than ever.

GA4 migrations left many setups broken, signal loss hides gaps, and decisions made on bad data compound. A periodic health check is cheap insurance against expensive mistakes.

01

GA4 migrations left hidden gaps

Many accounts were migrated to GA4 quickly and incompletely. Conversions, events and ecommerce tracking are often silently wrong.

02

Bad data compounds

Decisions made on inaccurate numbers ripple through budget, strategy and reporting. The cost of getting it wrong grows over time.

03

Consent and signal loss create blind spots

Privacy changes mean data can be missing or modelled. Knowing where the gaps are is part of reading the numbers correctly.

04

Tags drift over time

Sites change, tags break, duplicates creep in. Without periodic auditing, tracking quietly degrades.

05

An audit should end in insight

The point is not just a clean setup, but knowing what the data now tells you and what to do next.

What brands ask about analytics audits.

What is the purpose of an analytics audit?

An audit evaluates your current data collection and reporting setup to ensure accuracy and completeness. It identifies gaps or errors in tracking, so you can make informed decisions based on reliable data.

How can analytics consultancy benefit my business?

Consultancy provides expert guidance on setting up, managing and interpreting your data. It ensures you capture valuable user behaviour and performance metrics, leading to smarter decisions and better customer experiences.

What does a Google Analytics health check involve?

A health check reviews your current setup to confirm accurate data reporting. It assesses tracking implementation, configuration settings, and identifies any errors that may affect data integrity.

Why is Google Tag Manager auditing important?

Auditing GTM ensures your data tracking is accurate and efficient. It verifies that all tags are correctly implemented, firing as intended, and not causing conflicts or data discrepancies.

How often should I conduct an analytics audit?

At least annually, or whenever significant changes are made to your website or marketing strategies. Regular audits maintain data accuracy and keep your measurement aligned with evolving business needs.

What will the audit actually deliver?

A documented review of your tracking implementation, admin configuration, setup errors and performance data, with prioritised resolutions, so you know exactly what to fix and why.
