Google Analytics 4 Setup for Lead Generation: The Complete Guide

Google Analytics 4 (GA4) has replaced Universal Analytics as Google’s standard analytics platform. For businesses focused on lead generation, properly configured GA4 provides crucial insights into which marketing efforts drive enquiries and conversions. Without accurate tracking, you’re essentially flying blind with your marketing budget.

This guide walks through setting up GA4 specifically for lead generation businesses in New Zealand.

Why GA4 Matters for Lead Generation

Understanding your analytics isn’t optional—it’s essential for profitable marketing.

What GA4 Tells You

Which channels generate leads: Know if Google Ads, Facebook, or organic search delivers your enquiries
User journey insights: Understand how visitors interact with your site before converting
Content performance: Identify which pages contribute to lead generation
Campaign effectiveness: Measure ROI on specific marketing campaigns
Audience behaviour: Learn about your website visitors

Key Differences from Universal Analytics

GA4 represents a fundamental shift in how Google approaches analytics:

Event-based model: Everything is an event, not just pageviews
Cross-platform tracking: Better mobile app and website integration
Privacy-focused: Designed for a cookieless future
Machine learning: Predictive metrics and insights
Flexible reporting: Customisable reports and explorations

Setting Up GA4: Step by Step

Follow these steps to implement GA4 on your website.

Step 1: Create a GA4 Property

Go to analytics.google.com
Click Admin (gear icon)
In the Property column, click Create Property
Enter your property name (your business name)
Select your reporting time zone (NZ) and currency (NZD)
Click Next and complete business information
Accept terms and create the property

Step 2: Set Up a Data Stream

A data stream connects your website to GA4:

In your new property, click Data Streams
Click Add Stream and select Web
Enter your website URL and stream name
Click Create Stream
Copy your Measurement ID (starts with G-)

Step 3: Install the Tracking Code

Add GA4 to your website using one of these methods:

Google Tag Manager (Recommended):

Create a new tag in GTM
Select Google Analytics: GA4 Configuration
Enter your Measurement ID
Trigger on All Pages
Publish your container

Direct Installation: Add this code to your website’s <head> section:

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'G-XXXXXXXXXX');
</script>

Replace G-XXXXXXXXXX with your Measurement ID.

Step 4: Verify Installation

Confirm GA4 is working:

Visit your website in a new browser tab
In GA4, go to Reports → Realtime
You should see your visit appearing
Use Google Tag Assistant extension for detailed verification

Tracking Lead Generation Events

GA4’s power comes from tracking meaningful events beyond pageviews.

Essential Events for Lead Generation

Configure these events to track your leads:

Form Submissions:

Contact form completions
Quote request submissions
Newsletter signups
Booking form completions

Phone Calls:

Click-to-call button clicks
Phone number link clicks

Engagement Events:

Scroll depth
Time on page
File downloads
Video views

Setting Up Form Tracking

Method 1: Thank You Page Tracking

If forms redirect to a thank you page:

Go to Admin → Events
Click Create Event
Name it form_submission
Add condition: page_location contains thank-you
Save the event

Method 2: GTM Form Submission Trigger

For forms that don’t redirect:

In GTM, create a new trigger
Select Form Submission
Configure to fire on your form(s)
Create a GA4 Event tag triggered by this
Publish

Method 3: Enhanced Measurement

GA4 can automatically track some forms:

Go to Admin → Data Streams
Click your web stream
Enable Enhanced Measurement
Ensure Form Interactions is on

Setting Up Call Tracking

Track phone number clicks:

In GTM, create a trigger for clicks on tel: links
Create a GA4 Event tag named phone_click
Add parameters for phone number if tracking multiple
Publish

For full call tracking (actual calls, duration, etc.), consider dedicated call tracking software that integrates with GA4.

Configuring Conversions

Mark important events as conversions for reporting and optimisation.

Marking Events as Conversions

Go to Admin → Events
Find your lead generation events
Toggle Mark as conversion on

Key events to mark as conversions:

Form submissions
Quote requests
Phone clicks
Booking completions
Chat initiations

Conversion Value

Assign values to conversions for ROI calculations:

When creating the event, add a value parameter
Or modify existing events to include value
Use estimated lead values based on your conversion rates and average sale

Example: If 20% of leads become customers worth $2,000 average, each lead is worth approximately $400.

UTM Parameters and Campaign Tracking

Proper UTM tagging ensures accurate attribution.

UTM Parameter Basics

Add these parameters to your marketing URLs:

utm_source: Traffic source (google, facebook, newsletter)
utm_medium: Marketing medium (cpc, social, email)
utm_campaign: Campaign name (spring-sale, brand-awareness)
utm_content: Ad or content variation (optional)
utm_term: Keyword (optional, mainly for paid search)

UTM Examples

Google Ads:

?utm_source=google&utm_medium=cpc&utm_campaign=plumbing-services

Facebook Ads:

?utm_source=facebook&utm_medium=paid-social&utm_campaign=lead-gen-jan

Email Campaign:

?utm_source=newsletter&utm_medium=email&utm_campaign=monthly-update

Building UTM URLs

Use Google’s Campaign URL Builder or create a spreadsheet system:

Document all active campaigns
Create consistent naming conventions
Generate URLs systematically
Track which URLs are in use

Setting Up Audiences

Audiences in GA4 help you understand and remarket to specific user groups.

Valuable Audiences for Lead Gen

Create these audiences:

Converters:

Users who completed any conversion event
Use for: Exclusion, lookalike creation

High-Intent Visitors:

Users who viewed key pages (pricing, contact, services)
Use for: Remarketing

Engaged Visitors:

Users with session duration > 2 minutes
Users who viewed 3+ pages
Use for: Remarketing

Form Abandoners:

Users who started but didn’t complete forms
Use for: Targeted remarketing

Common Setup Mistakes

Avoid these frequent GA4 configuration errors:

Mistake 1: Not Setting Up Conversions

Many businesses install GA4 but never configure conversion tracking. Without this, you can’t measure marketing effectiveness.

Mistake 2: Inconsistent UTM Tagging

Using different naming conventions or forgetting UTMs entirely breaks attribution. Create and enforce standards.

Mistake 3: Ignoring Cross-Domain Tracking

If you have multiple domains (blog on subdomain, separate booking system), configure cross-domain tracking to maintain user sessions.

Mistake 4: Not Linking Google Ads

Without linking, you miss conversion data for campaign optimisation and can’t use GA4 audiences in Google Ads.

Mistake 5: Checking Data Too Soon

GA4 data can take 24-48 hours to fully process. Don’t make decisions based on incomplete real-time data.

Frequently Asked Questions

Is GA4 free?

Yes, GA4 is free for most businesses. Google Analytics 360 (paid) exists for enterprise needs, but the standard GA4 handles millions of events monthly.

How long until I have useful data?

Basic traffic data appears within minutes. However, meaningful conversion data requires volume—typically 2-4 weeks of consistent traffic to identify patterns.

Do I need Google Tag Manager?

Not strictly, but GTM makes GA4 management significantly easier, especially for tracking events like form submissions. We recommend GTM for most businesses.

GA4 is designed with privacy in mind. Implement a consent management solution, configure GA4’s consent mode, and follow data retention best practices.

Can I track phone calls properly?

GA4 can track click-to-call events. For full call tracking (actual connections, call duration, recordings), you’ll need dedicated call tracking software that integrates with GA4.
