Beyond Pageviews: How to Track High-Value Lead Form Submissions in GA4 on WordPress

Why Default GA4 Tracking Leaves Sydney Businesses in the Dark

If you are running a service-based business in Sydney, your website has one primary job: generating high-quality leads. Whether you are a commercial builder, a boutique law firm, or a specialized medical practice, a visitor simply landing on your website is not a win. The real win happens when they fill out your contact form, request a quote, or click to call.

By default, Google Analytics 4 (GA4) does an excellent job of tracking basic metrics like pageviews, scroll depth, and external link clicks. However, it falls short when it comes to understanding who is actually submitting your forms. If your contact forms use modern AJAX loading (where the form submits dynamically without redirecting the user to a new page), GA4’s standard tracking will likely miss it entirely.

To scale your business, optimize your SEO, and make sure your Google Ads budget isn’t being wasted, you need precision tracking. In this guide, we will walk you through setting up custom GA4 events on your WordPress website so you can track your leads with 100% accuracy.

The Two Best Methods for Tracking WordPress Form Submissions

Depending on how your WordPress site is built, there are two primary ways to track custom form events in GA4. We will cover both the simple Thank You Page Redirect method and the more robust Google Tag Manager (GTM) approach.

Method 1: The Thank You Page Redirect (No-Code & Highly Reliable)

This is the most straightforward method. When a user successfully fills out your Contact Form 7, Gravity Forms, WPForms, or Elementor Form, they are automatically redirected to a dedicated confirmation page (e.g., /thank-you/).

Because this page can only be accessed by submitting a form, tracking visits to this URL gives you an exact count of your leads.

• Step 1: Create a new page in WordPress called “Thank You” and set its URL slug to thank-you. Ensure this page is set to noindex so search engines don’t index it.
• Step 2: Go to your form plugin settings and configure the redirect URL to point to your new thank-you page.
• Step 3: Open your GA4 property and navigate to Admin > Custom Definitions > Create Custom Event.
• Step 4: Name your event something clear, like lead_form_submission.
• Step 5: Set the matching conditions to: event_name equals page_view AND page_location contains /thank-you/.

Now, every time a user reaches that page, GA4 will record a custom conversion event.

Method 2: Google Tag Manager (Best for AJAX & Multi-Step Forms)

If you prefer to keep users on the same page after submitting a form, you need to use Google Tag Manager (GTM) to listen for the form submission event.

• Step 1: Install GTM on WordPress. The cleanest way to do this without bloating your site is by pasting the GTM container code into your child theme’s header.php file, or using a lightweight plugin like WPcode.
• Step 2: Enable Form Variables. In GTM, go to Variables > Configure and check all boxes under the “Forms” category (Form ID, Form Classes, Form Target, etc.).
• Step 3: Create a Form Trigger. Go to Triggers > New. Choose “Form Submission” as the trigger type. Select “Some Forms” and set it to fire when Form ID equals your specific form’s ID (which you can find by inspecting your form element in your browser).
• Step 4: Create the GA4 Event Tag. Go to Tags > New. Select “Google Analytics: GA4 Event”. Select your GA4 Configuration Tag, and set the Event Name to contact_form_submit.
• Step 5: Link and Publish. Associate your new Form Trigger with this GA4 Event Tag. Click “Preview” to test it in GTM Debug Mode, then click “Submit” to publish your changes.

How to Turn Your Custom Events into Trackable GA4 Conversions

Setting up the event is only half the battle. To use this data for your marketing decisions, you must mark these events as conversions.

Once your custom events start registering (which can take up to 24 hours to show in your standard GA4 reports), navigate to Admin > Conversions in your GA4 dashboard. Locate your custom event name (e.g., lead_form_submission) and simply toggle the switch to Mark as conversion.

By doing this, you can now see exactly which channels—organic SEO, local search, or paid Google Ads—are driving actual business revenue, rather than just empty clicks.
