GA4 Audit & Setup That Gives You Data You Can Actually Trust

If you're making marketing decisions based on GA4 data, that data better be right. Most GA4 implementations we audit have significant tracking gaps — missing conversions, misconfigured events, broken cross-domain tracking, or bot traffic inflating numbers. We fix it.

What Is a GA4 Audit?

A GA4 audit is a systematic review of your Google Analytics 4 implementation to identify tracking errors, missing data, configuration issues, and optimisation opportunities. It covers your data streams, event tracking, conversion setup, audience definitions, custom dimensions, Google Tag Manager configuration, and integration with Google Ads and other platforms. The goal is to ensure the data you're using to make decisions is accurate, complete, and reliable.

Common GA4 Issues We Find

  • Missing conversion tracking. The number one issue. Form submissions, phone calls, or purchases aren't being tracked as conversions — meaning your Google Ads campaigns can't optimise for what matters.
  • Broken cross-domain tracking. If your checkout, booking system, or forms sit on a different domain, sessions break and conversions get attributed to the wrong source.
  • No consent mode. Australian privacy law requires user consent for certain tracking. Without consent mode, you're either non-compliant or losing a significant portion of your data.
  • Self-referral inflation. Payment gateways (Stripe, PayPal, Afterpay) showing as traffic sources, inflating referral traffic and breaking session attribution.
  • Bot traffic. Automated bot traffic inflating session counts and distorting engagement metrics. GA4's built-in bot filtering is better than Universal Analytics but still misses some.
  • Default channel grouping errors. Traffic landing in "(Other)" or being misclassified because UTM parameters are inconsistent or missing.

Frequently Asked Questions

How long does a GA4 audit take?

A comprehensive GA4 audit typically takes 1–2 weeks from kickoff to delivery. Simple implementations (single domain, standard ecommerce) are usually completed in 1 week. Complex setups (multiple domains, custom events, app + web) may take 2–3 weeks.

How much does a GA4 audit cost?

GA4 audit pricing ranges from $2,000 to $5,000 depending on the complexity of your implementation. A full GA4 setup (new implementation from scratch) typically costs $3,000 to $8,000. View our pricing page for details.

Can I do a GA4 audit myself?

You can check basic settings, but a thorough audit requires expertise in GA4's data model, Google Tag Manager, consent management, and cross-platform tracking. Most in-house teams we work with are surprised by the issues a professional audit uncovers — particularly around conversion tracking accuracy and cross-domain configuration.

Do I need Google Tag Manager with GA4?

Technically no — GA4 can be implemented via the gtag.js snippet. But for any business running ads, tracking multiple conversion types, or needing consent management, Google Tag Manager is essential. It gives you control over your tracking without requiring developer involvement for every change.
