How often do you use Form Submission trigger in GTM

[swiftpropel]

The GTM form submission trigger is sometimes a hit or a miss due to the construction of the form (e.g., AJAX, single-page apps). I would normally suggest that it should be used in conjunction with other techniques, such as listening to button clicks or URLs changing on submission, or it can be better used as a custom event listener. You can test anything to get what fits your particular setupof forms.

In my experience forms that work with that trigger already work natively in GA4 with the form_submit event. Thus you can often just create a key event tied to that and you’re done.

When this doesn’t work I usually see whether form redirection is possible and use the thank-you page for tracking conversions… still the gold standard.

If not then plan B in GTM, button clicks tied to a unique form identifier.

Its not reliable enough. Better to use a thank you page or a custom datalayer event as the trigger.

It definitely works but the tracking of submissions won’t be as accurate as you can make it with thank you page.

The reason is there is no way to view that page until someone fills out the form. The same page forms & button clicks tend to be less accurate in measuring the conversions.

The built-in **form submission trigger in GTM** can be hit or miss because it depends on how the form is coded (some use AJAX or don’t fire a standard submit event). A more reliable option is to track either:

* A **thank-you page load** (if the form redirects after submission), or
* An **element visibility trigger** on something unique that only appears after a successful submission (like a “Thank you for submitting” message).

Both of these give you a cleaner and more consistent signal compared to the generic form submission trigger.
