Google Tag Manager Audit

Is your GTM setup structured, controlled and working as expected on the journeys that matter most? This audit uses a clear review methodology to identify governance issues, trigger risks, implementation weaknesses and tagging problems that could undermine measurement quality.

Container review Assesses structure, naming conventions, organisation and maintainability.
Tag and trigger review Checks whether key tags and triggers appear correctly configured and sensibly controlled.
Targeted live validation Tests key journeys and tagging behaviour using practical validation tools and checks.
Clear recommendations Provides prioritised actions to reduce risk and improve tagging quality.

Why a GTM Audit Matters

Google Tag Manager is often the operational layer behind analytics, advertising and conversion tracking, but over time containers can become cluttered, inconsistent and difficult to manage safely.

This audit reviews your GTM setup and validates key live tagging behaviour to identify governance issues, implementation weaknesses and the improvements most likely to reduce risk.

What This Audit Helps Uncover

Container clutter and control issues

Identify duplicated, legacy or poorly organised tags, triggers and variables that make GTM harder to manage safely.

Tagging and trigger weaknesses

Spot key configuration issues, brittle logic and obvious firing risks affecting important tags and journeys.

Measurement risk

Assess whether the current GTM setup provides a reliable operational foundation for analytics and marketing tags.

Who This Is For

  • Teams using GTM to manage analytics and marketing tags
  • Organisations concerned about implementation quality or governance
  • Businesses with legacy containers that have grown messy over time
  • Marketing teams who want more confidence in how tracking is deployed

Audit Scope

Container Structure Review

  • Review of container organisation and maintainability
  • Assessment of naming conventions for tags, triggers and variables
  • Identification of duplicate, redundant or legacy assets
  • Review of folder structure and overall clarity
  • High-level review of versioning and publishing discipline where visible

Tag, Trigger and Variable Review

  • Review of key analytics and marketing tags within the container
  • Assessment of trigger logic for important tags and interactions
  • Review of variable setup where relevant to tagging reliability
  • Identification of obvious risks such as overlap, duplication or brittle logic
  • High-level review of custom HTML usage and associated implementation risk

Targeted Live Validation

  • Practical validation of selected key tags and journeys using browser-based testing tools
  • Checks of whether important tags appear to fire in the expected scenarios
  • Basic validation of key data layer elements where relevant to the audit scope
  • Review of important page types or journeys agreed at the start of the project

Consent and Deployment Review

  • High-level review of visible consent-related configuration within GTM
  • Basic checks of key tag behaviour in relation to consent where feasible
  • Review of whether GTM appears present across the agreed key pages or journeys
  • Identification of obvious deployment or governance risks

Findings and Recommendations

  • Summary of the main issues identified
  • Prioritised list of recommended actions
  • Clear explanation of why each issue matters
  • Assessment of overall container quality and maintainability

What You Receive

Following the audit you will receive a concise set of Audit Results summarising the key findings, risks and recommended next steps.

Audit deliverables

  • Summary of key issues identified
