NEEDS ATTENTION

Sound familiar?

The problems we hear every single week

If any of this feels a little too close to home, your GA4 property probably needs a proper look under the hood.

Attribution Conflict Detected

20–30% gap

is now considered a "normal" difference between GA4 and Google Ads conversion counts — anything wider usually points to a real configuration problem, not just methodology.

Problems Hiding Behind Clean Dashboards

~40% of properties

have event configuration errors that lead to incomplete or inaccurate GA4 data, often with no visible warning that anything is wrong.

Numbers Nobody Can Fully Explain

80%+ of websites

carry at least one analytics or tracking configuration issue, ranging from duplicate scripts to broken event tags, per large-scale audit research.

Data Quietly Leaking Away

40–50% of visitors

vanish from GA4 reporting the moment they decline cookies under a Basic Consent Mode setup — with no modelling to recover the gap.

The audit

Uncover the mysteries of GA4

A GA4 audit doesn’t just check that everything is configured correctly — it also checks how healthy your data actually is. We split every audit into three parts.

Confirming you’re collecting data from your websites & apps, that every setting is correct, and that any advanced custom data collection is properly configured.

PART 02 Data Health Checks

Running data health checks across every area of your GA4 property to determine whether your data can genuinely be trusted as a source of truth.

PART 03 Tagging Checks

Verifying your GA4 setup service and GTM tags are firing correctly on every page — including your full conversion tracking setup.

Checking your UTM tags and channel attribution is healthy.

Events & Conversions Health

Why it matters

Why are GA4 audits important?

GA4 is a cornerstone of your marketing tech stack. Keeping it optimised — and your data robust — is essential for the success of your online business. A healthy GA4 lets you:

Evaluate your marketing mix — see what's genuinely driving conversions, so paid and organic teams know their real contribution.
Identify high-performing content — let SEO and content teams focus on pages that actually move the needle.
Understand your audience — demographic and regional insight for sharper targeting.
Spot journey pain points — find and fix friction in the customer experience.
Analyse product performance — for ecommerce, optimise offers and strategy on real data.

GA4 gives you powerful tools — when it's set up right

Custom Exploration Reports

Build your own funnels, path explorations & segment overlaps.

Audience Builder

Create remarketing audiences and push them straight to Google Ads.

Attribution Tools

Pick the right model and understand each touchpoint's true impact.

Cadence

How often should you run a GA4 audit?

It depends on the type of check — here’s what we recommend.

EVERY 2 YEARS

Configuration Checks

GA4 is well-established now. Major features that change these checks are rare, so once every couple of years is usually enough.

EVERY 6–12 MONTHS

Data Health Checks

Websites and browsers change regularly, and both can quietly affect GA4 data quality — so review health at least once or twice a year.

ONGOING

Tagging Checks

Check conversion data frequently. Any dip in key events means the tags feeding them need testing immediately — that’s your conversion tracking setup at work.

Why it matters

Frequently asked questions

What is a GA4 audit service?

A GA4 audit service is a structured review of your Google Analytics 4 property — configuration, data health and tagging — to confirm your data can be trusted and to surface issues affecting your marketing decisions.

Do you offer a GA4 setup service as well as audits?

Yes. Alongside audits we provide a full GA4 setup service and conversion tracking setup — configuring events, key events, ecommerce and consent so your property collects the right data from day one.

Why do GA4 and Google Ads show different conversions?

They use different attribution methods, conversion windows and identity signals. Large or unexplained gaps can also indicate missing tracking, duplicate conversions or configuration problems — exactly what a GA4 audit uncovers.

Are you a GA4 consultant UK businesses can work with directly?

Yes — we’re a specialist Google Analytics consultant UK-based, working with ecommerce and lead-gen businesses across the UK and beyond on audits, setup and ongoing analytics management.

How long does a GA4 audit take?

Most audits are completed within a week or two depending on property complexity, followed by a consultation call to walk through the findings and your action plan.

Is there a free option?

Yes — start with our free GA4 audit checklist & template to review the essentials yourself before deciding on a full paid GA4 audit service.
