How can I create a GA4 Event to track form conversions using Webflow, Google Tag Manager, and Google Analytics 4?

To track form conversions in Webflow using GA4, you’ll need to use Google Tag Manager (GTM) to detect Webflow’s native form submission and send a GA4 event via GTM.

1. Set Up Google Tag Manager in Webflow

• Go to Project Settings > Custom Code in Webflow.
• In the Head section, paste your GTM container code (upper part).
• In the Body section, paste the GTM container code (lower part).
• Publish your Webflow site to apply the changes.

2. Enable Form Submission Trigger in GTM

• In GTM, click Triggers > New.
• Choose Form Submission as the trigger type.
• Enable "Check Validation" to avoid catching incomplete form submissions.
• Optional: For cleaner targeting, use Trigger Conditions like Page Path contains /contact or form-specific classes (if applicable).
• Name and save the trigger (e.g., “Webflow Form Submit”).

3. Configure GA4 Event Tag in GTM

• Go to Tags > New.
• Tag Type: Choose Google Analytics: GA4 Event.
• Choose or create your GA4 Configuration Tag (with your GA4 Measurement ID).
• Under Event Name, use something like form_submit (use snake_case, lowercase).
• Under Event Parameters, you can add:
• parameter name: form_location, value: {{Page Path}}
• parameter name: form_id, value: {{Form ID}} (if available)
• In the Triggering section, select the form submission trigger created earlier.
• Save and publish the GTM workspace.

4. (Optional) Test Using GTM Preview and GA4 DebugView

• In GTM, click Preview and enter your website URL to open the GTM debug pane.
• Submit a form; ensure your form submission trigger fires.
• Go to GA4 > Admin > DebugView to verify the event is received by GA4.

5. Mark the Event as a Conversion in GA4

• In GA4 > Events, find your form_submit event after some data has come in.
• In the event list, click the toggle to mark it as a conversion.

Summary

To track form conversions in Webflow using GA4, install GTM in your Webflow project, create a form submission trigger, and send a GA4 event when a form is submitted. Then, mark this event as a conversion in GA4 to track it in reports.
