1. Set Up Proper Tracking for GA4
With third-party cookies becoming obsolete and stricter privacy laws like GDPR and CCPA evolving, GA4’s event-based tracking model is a game-changer. Instead of relying on cookies, GA4 uses machine learning and first-party data to provide a more complete view of user behaviour.
Steps to Set Up GA4 for PPC Campaigns
- Link Google Ads to GA4: Connect your Google Ads account to GA4 to ensure seamless data sharing and automatic import of cost and campaign metrics.
- Enable Enhanced Measurement: GA4 automatically tracks events like scrolls, clicks, and video interactions. Use these to monitor key touchpoints.
- Create Custom Events: Set up custom events to track actions unique to your business, such as form submissions or specific product interactions.
- UTM Tagging: Use consistent UTM parameters in your Google Ads campaigns to track ad performance across GA4 reports.
2. Understand PPC Traffic with GA4’s New Data Model
Unlike Universal Analytics, which was session-based, GA4 focuses on events and users. This shift provides a more granular view of how users interact with your ads and website.
Key PPC Insights with GA4
- Engaged Sessions: Instead of relying on bounce rates, GA4 measures engagement, such as sessions lasting longer than 10 seconds or users taking specific actions.
- Path Exploration: Use the Path Exploration tool to see the user journey from clicking an ad to completing a conversion.
- Audience Overlap: Understand how PPC visitors overlap with other traffic sources, like organic or social, to optimise cross-channel strategies.
By focusing on user-centric metrics, you’ll gain a clearer picture of how PPC traffic contributes to your overall marketing efforts.
3. Track Key PPC Metrics in GA4
Google Analytics 4 offers enhanced reporting capabilities for PPC advertisers, making it easier to track the metrics that matter.
Must-Track Metrics for PPC Campaigns
- Cost Per Conversion (CPA): Import your Google Ads conversion data into GA4 to see how much you’re paying for each lead or sale.
- Lifetime Value (LTV): Use GA4’s predictive analytics to estimate the lifetime value of users acquired through PPC.
- Conversion Paths: Understand which campaigns or keywords contribute to multi-touch conversions.
- Engagement Rate: Assess how PPC users interact with your website to gain insights into landing page performance.
Pro Tip: Create a custom insights dashboard in GA4 to track PPC-specific metrics like ROI, CTR, and cost-per-click alongside engagement data.
4. Use Predictive Analytics to Enhance PPC Campaigns
One of GA4’s standout features is its predictive analytics capabilities, powered by AI. These features allow you to forecast user behaviour and optimise campaigns proactively.
Predictive Metrics for PPC
- Purchase Probability: Identify audiences most likely to convert and target them with PPC campaigns.
- Churn Probability: Use this data to retarget users at risk of abandoning your site or cart.
- Revenue Predictions: Focus ad spend on campaigns or audiences expected to generate the highest revenue.
These insights guide audience segmentation and bidding strategies, ensuring your PPC budget is spent on high-value opportunities.
5. Analyse Cross-Channel Attribution
In 2025, single-channel attribution is outdated. Users interact with multiple touchpoints before converting, and GA4’s advanced attribution modelling provides a comprehensive view of the customer journey.
Attribution Models in GA4
- Data-Driven Attribution: This model uses AI to assign credit to each touchpoint, including PPC ads, based on their actual contribution to conversions.
- Multi-Channel Funnels: Analyse the role PPC plays in assisting conversions, even if it’s not the final touchpoint.
- Custom Attribution Windows: Adjust attribution windows to match your sales cycle and better understand PPC’s impact.
This cross-channel view is invaluable for optimising your PPC campaigns and budget allocation.
6. Optimise Landing Pages with User Behaviour Data
Landing page performance is critical to PPC success. GA4 provides detailed insights into how users interact with your pages, allowing you to make data-driven improvements for better conversions.
Key Reports for Landing Page Optimisation
- Scroll Tracking: Analyse how far PPC users scroll, identifying where engagement drops off.
- Engagement by Device: Understand how mobile and desktop users behave differently, then tailor landing pages accordingly.
- Session Replays (via GA4 integrations): Use tools like Hotjar, integrated with GA4, to watch how PPC users interact with your landing pages.
By understanding user behaviour, you can improve page load speed, simplify navigation, and create more compelling CTAs.
7. Use Audiences for Retargeting in Google Ads
One of the most powerful integrations between GA4 and Google Ads is audience creation. With GA4, you can build highly detailed audiences based on user behaviour and retarget them effectively in your PPC campaigns.
Examples of Retargeting Audiences
- Users who abandoned their carts but spent more than five minutes on your site.
- Visitors who engaged with a specific product page but didn’t convert.
- High-value customers who made repeat purchases in the last 90 days.
These dynamic audiences update in real time, enabling you to target users with relevant ads and maximise conversion potential.
8. Leverage Real-Time Reporting for Quick Adjustments
In 2025, PPC success relies on agility. GA4’s real-time reporting tools allow you to monitor campaign performance as it happens, enabling immediate adjustments to bids, budgets, or targeting.
Real-Time Insights to Monitor
- Traffic spikes from specific campaigns or keywords.
- Geographical trends revealing new high-performing regions.
- Sudden drops in engagement that could indicate landing page issues.
Quickly responding to these insights ensures your campaigns remain effective and cost-efficient.
9. Monitor Privacy and Compliance in GA4
With increasing privacy regulations, maintaining compliance is more important than ever. GA4 is designed to be privacy-centric, but advertisers must still take steps to ensure data protection.
Tips for PPC Compliance
- Use GA4’s consent mode to respect user opt-ins and opt-outs.
- Enable IP anonymisation to protect user identities.
- Regularly review data retention settings to align with privacy laws.
By prioritising privacy, you build trust with your audience and avoid costly penalties.
10. The Role of AI in GA4 and PPC Campaigns
As AI continues to evolve, its role in Google Analytics and PPC is becoming increasingly significant. In 2025, expect more AI-powered features in GA4, including:
- Automated Insights: Alerts about anomalies or opportunities in your PPC performance.
- AI-Driven Recommendations: Suggestions for improving targeting, ad copy, or bidding strategies.
- Enhanced Predictive Metrics: Deeper forecasting tools for even greater precision.
