How To Add Value to a GA and GTM Audit
Most GA4 and GTM audits focus on technical accuracy — checking tags, validating triggers, and fixing broken event tracking. While that’s important, it’s not enough.
If your audit doesn’t inspire action, build trust, and connect analytics to business outcomes, it’s just another report that gets ignored.
At MeasureCamp London 2025, I shared a session on how to make GA4 and GTM audits genuinely valuable — not just technically correct, but strategically useful. Here’s a summary of the key takeaways from my presentation.
1. Change the Perception: From Technical to Strategic
Too often, audits are viewed as compliance tasks. A great GA4/GTM audit reframes that.
It shows how accurate data supports decisions that improve marketing performance, customer experience, and business growth.
Audits should empower teams, not just highlight problems.
2. Be Honest
Be transparent about what an audit can and can’t achieve. GA4 isn’t an accounting system — it’s designed for insight, not perfect accuracy.
Don’t over-promise. Some tracking fixes will need input from developers or backend teams. The goal is to build trust, not false expectations.
3. Ask Lots of Questions
The best insights come from curiosity. Understand the client’s business model, key user journeys, and what success looks like for them.
An audit without context is just a list of fixes.
4. Use Their Language
Avoid jargon. Talk about conversions, revenue, and customer experience — not tags, triggers, and data layers.
When stakeholders understand what you’re saying, they act on your recommendations.
5. Add Value with Measurement and Insight
Here are some practical ways to go beyond the basics:
Measurement Plan – Align business objectives with user goals and KPIs.
Regular Updates – Provide transparent weekly progress summaries: what was done, what’s next, key risks, and hours used.
Core Web Vitals – Use Google’s performance metrics to link analytics with site speed and user experience.
Automatic Alerts – Set triggers for sudden drops in conversions or traffic.
AI UTM Analysis – Use AI tools to identify poor UTM structures and suggest consistent naming conventions.
Event Values – Assign a value to key GA4 events based on conversion rate and lifetime value.
Device Mining Dashboard – Analyse conversion performance by device type, OS, and browser. Credit to Craig Sullivan and Charles Meaden for this concept. Get the dashboard here.
Session Replay – Tools like Microsoft Clarity add qualitative context to GA4 metrics.
BigQuery Export – Unlock unsampled GA4 data for advanced analysis and cost control.
Knowledge Transfer – Train teams via Microsoft Teams or Google Meet to interpret their own data. Empowerment is a form of added value.
6. The Outcome: Trust, Insight, and Collaboration
A truly valuable GA4/GTM audit builds stronger partnerships. It delivers insights that clients can act on, transparency that drives trust, and measurable improvements that reinforce your credibility.
Adding value isn’t about doing more work — it’s about changing how your work is perceived.
