Tracking Reliability: End-to-End Audit

Find Out If Your Marketing Data Is Reliable Enough To Make Decisions

End-to-End Audit — £1,499 one-off

The Tracking Reliability Diagnostic is the £1,499 End-to-End Audit: a paid investigation with agreed practical tests from customer action to recorded result. It is not the free questionnaire-based tracking-risk assessment.

We review the agreed GA4, GTM and connected-platform configuration, then trace test activity through accessible destinations. We distinguish tracking faults from expected reporting differences and state what remains unverified.

You receive evidence, a prioritised action plan and a walkthrough of the findings. Fixes are separate

One fixed-scope engagement. No ongoing commitment

Why Tracking Reliability Matters

Many businesses have analytics dashboards filled with numbers but still cannot answer simple questions:
Are our conversions being tracked correctly?
Can we trust our marketing reports?
Are advertising platforms receiving accurate data?
Are we losing valuable customer journey information?
Which channels are genuinely driving results?

Missing events, duplicate conversions, incorrect values or inconsistent definitions can make reports difficult to interpret. The audit investigates the agreed journeys and documents the evidence and likely reporting consequences.

Finding a discrepancy does not, by itself, prove lost revenue or establish the value of a repair.

What the agreed audit can cover

1. GA4 Configuration and Data Review

We review the agreed GA4 configuration and available data against your measurement requirements. Checks may include:

The goal is simple: help you understand whether your GA4 property is providing reliable insights.

2. Google Tag Manager & Tracking Implementation Review

Incorrect tagging can silently affect your reports.

We analyse your tracking implementation to identify:

We separate what the configuration shows from what agreed practical tests confirm, including any gaps in destination evidence.

3. Conversion Tracking Validation

We agree which customer actions to test, such as:

We trace those agreed tests to the accessible destination records. Definitions distinguish a click from a completed action, and an enquiry from a qualified lead. Any access, isolation or processing limitations are documented.

4. Campaign & Attribution Health Review

Marketing platforms often report different numbers because of differences in tracking methods and attribution models.

We review:

We aim to identify where measurement gaps exist and provide practical recommendations to improve reporting confidence.

How the End-to-End Audit works

Step 1

Understand Your Measurement Setup

We review your business goals, marketing channels, website structure and current analytics environment.

Step 2

Analyse Tracking Health

We inspect the agreed configuration and carry out controlled practical tests, checking the available event and destination evidence.

Step 3

Provide Clear Findings

You receive findings, supporting evidence, limitations and a prioritised action plan, with a walkthrough of what the results mean.

Step 4

Agree Any Follow-On Work

Repairs, setup and ongoing management are separate, optional work. The audit does not include implementation changes or require an ongoing commitment.

What you receive from the audit

The End-to-End Audit provides:
A clear view of your current tracking health
Identification of measurement gaps and risks
Practical recommendations for improvement
Better understanding of attribution accuracy
A roadmap to improve reporting confidence
We focus on actionable insights rather than complicated technical explanations.

Why Choose Attribution Metrics?

We agree the systems, journeys and access before work starts. Findings distinguish observed results, configuration risks and checks that could not be completed.

The report supports decisions about repairs or further work. It does not certify that all tracking is complete, establish legal compliance or guarantee a commercial outcome.
