Ecommerce GA4 Audit Service

Understand the gap between a completed order and the sale in your reports

We review ecommerce measurement for missing purchases, duplicate transactions, inconsistent values and gaps in the shopping journey. Choose a review of existing configuration and reports, or practical testing from product interaction to recorded result.

Why Your Ecommerce Business Needs a GA4 Audit

Google Analytics 4 is powerful, but only when it is collecting accurate and meaningful data. Many ecommerce websites face issues such as:

Incorrect purchase tracking
Missing ecommerce events
Duplicate conversions
Revenue mismatches
Poor attribution visibility
Broken Google Tag Manager setups
Incomplete customer journey tracking

The audit investigates these issues, separates confirmed findings from unverified risks and provides practical recommendations.

Choose the depth of review: the £499 Read-Only Audit examines existing configuration and available reports, without live checkout tests. The £1,499 End-to-End Audit adds agreed practical tests, which can include test orders and destination records where access permits. Implementation and fixes are separate from both audits.

Our Ecommerce GA4 Audit Process

GA4 Configuration Review

We inspect GA4 property settings, data streams, filters and integrations against the agreed measurement requirements.

Ecommerce Event Tracking Audit

Our ecommerce tracking audit reviews essential GA4 ecommerce events, including:

The Read-Only Audit reviews existing event configuration and evidence. The End-to-End Audit adds agreed practical checks of events, parameters and destination records, with unverified areas clearly stated.

Google Tag Manager & Data Layer Analysis

We review your GTM implementation, tags, triggers, and ecommerce data layer to identify technical issues affecting data collection.

Revenue & Conversion Accuracy Check

We compare GA4 ecommerce data with your website platform and sales information to detect missing transactions, incorrect values, or tracking errors.

Attribution & Marketing Data Review

We compare campaign tracking, UTMs, attribution settings and conversion definitions to explain how credit is assigned. Reported credit is not proof of incremental sales.

Illustrative example: If your store shows £10,000 in orders but GA4 reports £9,200, we check whether the gap comes from how tax, delivery, discounts or refunds are counted — before assuming anything is broken. (This is an illustrative example, not a client case study.)

Why it matters

Frequently asked questions

Q. What is an Ecommerce GA4 Audit Service?

A. It reviews how your store’s activity reaches GA4 and the reports you use. The £499 Read-Only Audit uses existing configuration and evidence; the £1,499 End-to-End Audit adds agreed practical testing. Neither includes implementation fixes.

Q. Why should I conduct a GA4 audit for my ecommerce website?

A. An audit investigates missing or duplicate events, inconsistent values and reporting differences. It identifies supported findings and remaining uncertainties; it does not guarantee complete data or a revenue uplift.

Q. What does an ecommerce tracking audit include?

A. Our audit covers GA4 configuration, ecommerce events, Google Tag Manager, data layers, conversion tracking, revenue accuracy, and attribution analysis.

Q. Can you help if my GA4 revenue does not match my store sales?

A. Yes. We review transaction tracking, purchase events, revenue parameters, and integrations to identify why GA4 and your ecommerce platform may show different numbers.

Q. How can an ecommerce analytics consultant improve my reporting?

A. An ecommerce analytics consultant defines measurement requirements, investigates discrepancies and recommends changes. Implementation and ongoing management can be agreed separately when needed.
