To Make this work – your form must have a FORM ID in the HTML

e.g.

<form id="contact-form" action="script.php" method="post">
    <input type="hidden" name="redirect" value="http://www.opera.com" />
    <ul>

 

Log in to GTM

If you don’t already have a Container for your website – create one now

 

Once you’re set up and inside GTM

Check Variables are Set up to Allow Form ID Tracking

• Go to Variables
• Click Configure
• Scroll down to forms
• Click Form ID

 

Trigger – Set up Form ID Trigger

• Go to Triggers in left sidebar
• Click New
• Give the Trigger a Name – “Form Submitted”
• Click on the screen/box and to configure – select “Form Submission”
• For generic tracking of forms choose “All Forms”
• Leave the “Wait for Tags”* option for now. Increase if tracking doesn’t work
• Click Save

*Wait for tags gives GTM more time to fire the tags, before moving to the ‘thank you’ page.

Tag – Set up GA Event Tag

• Click “Tags” on left sidebar
• Give it a name – “GA Event – Form Submission”
• Click Box to configure – choose Universal Analytics
• Add Google Analytics UA Code*
• From the drop down menu – Track Type – Choose “Event”
• Several options should now appear:

• Name the Category – e.g. “Leads” for a contact form on your business website
• Action – e.g. “Form Submitted”
• Label – click the Lego icon and choose Form ID
• Scroll down to the second box and click to choose the trigger
• Click on Form Submitted trigger that we made earlier
• Click Save

 

*Found in Google Analytics>Admin>Property Settings

 

Instead of adding your GA Tracking ID, it’s often best to create a Variable for your ID so that it can be changed more easily etc.
