Tracking form submissions in Google Analytics 4 (GA4) involves sending an event to GA4 when a user successfully submits a form on your website. As of early 2026, this is primarily achieved through Google Tag Manager (GTM) and utilising GA4’s enhanced measurement or custom event configurations.
- Thank You Page Views: The simplest method – trigger a GA4 event when a user lands on the ‘thank you’ page after submission.
- Form Submission Events via GTM: GTM now features robust form handling triggers, allowing you to capture data directly from the form fields (e.g., name, email) and send it as custom event parameters.
- Enhanced Measurement: GA4’s enhanced measurement automatically tracks form interactions, but requires careful configuration to ensure accurate data capture and avoid duplicate counting.
- Server-Side Tagging: Increasingly popular in 2026 for data privacy, server-side tagging allows form submission data to be processed on your server before being sent to GA4, enhancing data control.
Australian businesses need to be particularly mindful of privacy regulations like the Privacy Act 1988 and the Australian Privacy Principles (APPs) when collecting and tracking form data. Ensure you have clear consent mechanisms in place and are transparent about what data you’re collecting and how it’s being used. Current systems include consent management platforms that integrate seamlessly with GA4 via GTM, helping maintain compliance.
