Google Analytics 4 (GA4) has changed the way we measure advertising performance — especially across paid media channels like Google Ads.
For advertisers looking to understand real business impact and not just surface metrics, GA4 offers deeper insight into user journeys, assisted conversions, and cross-device behaviour.
In this guide, we walk through how to effectively track your Google Ads performance using GA4, whether you’re running campaigns in New Zealand, Australia or globally.
Why GA4 Is Essential for Google Ads
- Session-based tracking is gone — events are now the core
- Attribution modelling is more flexible and insight-driven
- GA4 integrates directly with Google Ads for clearer conversion tracking
- Audiences created in GA4 can be synced directly to Google Ads campaigns
What You Need to Set Up First
1. Link Google Ads and GA4
Ensure both platforms are integrated in the GA4 Admin panel so conversions and audiences sync seamlessly.
2. Enable Enhanced Conversions and Cross-Domain Tracking
This ensures you’re measuring real business outcomes, especially for multi-touch journeys.
3. Define Key Events
Track high-intent actions: form submissions, checkout steps, phone calls, trial starts, etc.
4. Use Custom Conversions with Parameters
Custom events can include value, funnel step, product type — helping refine bidding logic.
How to Analyse Google Ads Traffic in GA4
- Navigate to User Acquisition and Traffic Acquisition reports to track sessions and conversions by source/medium
- Use Exploration Reports for deep path analysis and user journeys
- Build segments to compare branded vs non-branded keyword outcomes
- Measure Assisted Conversions to understand upper-funnel impact
- Analyse Time to Convert to match real buyer cycles
Use Case – Global SaaS Platform with AU Office
A SaaS company operating globally with headquarters in NZ and Australia used GA4 to unify its paid and organic reporting. By identifying drop-off points in the funnel and linking offline conversions to campaigns, they improved MQL-to-SQL ratios by 24% over two months.
Common Pitfalls to Avoid
- Only tracking default events like page_view or session_start
- Failing to import conversions into Google Ads
- Relying only on last-click attribution
- Not using audience creation for remarketing signals
Final Thoughts
If you’re still relying on outdated analytics or only looking at cost-per-click, you’re missing the big picture.
GA4 gives advertisers global and local clarity on what’s driving revenue, not just traffic — making it the cornerstone of modern Google Ads strategy.
