How this event is built in your container

Form Submission uses a Custom Event trigger that fires when your site pushes dataLayer.push({ event: 'form_submission' }) - the trigger is pre-configured to match this exact event name, so nothing needs adjusting after import.

Requirement: Your site needs to actually push that dataLayer event for the trigger to fire - the container listens for it, it doesn't generate it. Most WooCommerce sites get this from a data layer / enhanced ecommerce tracking plugin; check that dataLayer.push({event: 'form_submission', ...}) fires at the right moment using GTM's Preview mode before publishing.

The Google Analytics 4 tag itself is added automatically and wired to this trigger - you won't need to create or configure it by hand in GTM.

Troubleshooting

Form Submission doesn't fire at all in GTM Preview mode.
Confirm your site is actually pushing dataLayer.push({event: 'form_submission'}) - open the browser console and check the dataLayer array at the moment the action happens. If it's not there, the container has nothing to listen for.

The event fires, but values show up blank or undefined.
Check that the pushed object's key names match exactly (case-sensitive) - a mismatched key like "Value" instead of "value" will show as undefined in GTM's variable preview.

Form Submission fires twice for the same action.
You likely have both this container's tag and a manually-added Google Analytics 4 snippet both listening for the same action. Remove the manual one, or disable it, before publishing.

Frequently asked questions

What triggers the Form Submission event?

It fires automatically at the matching point in the WordPress visitor journey - the container builder wires up the correct trigger for you based on the standard dataLayer event for Form Submission, so there's nothing to configure manually beyond making sure your site actually pushes that event.

Why should I track Form Submission with Google Analytics 4 specifically?

It shows engagement further up the funnel, which Google Analytics 4 can use to build audiences and understand what leads to a purchase, even before the sale happens.

Is this free to set up?

Yes - the free tier covers 1 tracking platform at a time. If you need this event across several platforms in one container, unlocking full access covers all of them together.

Will this conflict with Google Analytics 4 code I already added manually?

It can, if the same event fires twice from two separate sources. Remove any manually-added Google Analytics 4 tag for this event before importing the generated container, or use GTM's Preview mode to confirm it only fires once.

How long does setup take?

A few minutes - select Google Analytics 4 and the Form Submission event in the wizard, enter your tracking ID, download the container, and import it into GTM.
