With the ease of point-and-click, track form submit buttons.
Track lead submissions, user registrations and user logins, on click submit forms and other form submit events. AJAX form submits work great, too.
Track all types of form details and form fields data that you would like to send to your analtyics tools, CRM and ad platforms.
Capturing the display success message after form submits means that you are not recording a success before the form is submitted.
