Unbounce + Google Ads Conversion Tracking Setup

I see this setup broken in about 35% of accounts I audit. The issue? Most people either rely on Unbounce’s native Google Ads integration (which doesn’t support Enhanced Conversions) or try to track conversions through redirect URLs, missing 20-30% of actual form submissions. Here’s how to set it up properly using GTM and Enhanced Conversions.

What You’ll Have Working By The End

Prerequisites

Step 1: Create the Google Ads Conversion Action

Log into Google Ads and navigate to Goals > Conversions. Click the plus button and select “Website.”

Set these specific values:

After saving, you’ll get a Conversion ID (format: AW-123456789) and Conversion Label (format: AbCdEfGhIj). Copy both - you’ll need them for GTM.

Step 2: Set Up Unbounce Form Event Tracking

Unbounce fires a ub-form-success event when forms are submitted successfully, but you need to capture the form data for Enhanced Conversions.

Add this script to your Unbounce page’s “Javascript” section:

// Enhanced conversion data collection for Unbounce
window.addEventListener('message', function(event) {
  if (event.data.type === 'ub-form-success') {
    // Get form data from the submission
    const formData = event.data.formData;
    
    // Push enhanced conversion data to dataLayer
    window.dataLayer = window.dataLayer || [];
    window.dataLayer.push({
      'event': 'unbounce_form_submit',
      'form_name': event.data.variant || 'default',
      'page_name': lp.jQuery('title').text(),
      'user_data': {
        'email_address': formData.email || '',
        'phone_number': formData.phone || formData.phone_number || '',
        'first_name': formData.first_name || formData.fname || '',
        'last_name': formData.last_name || formData.lname || '',
        'address': {
          'city': formData.city || '',
          'region': formData.state || formData.region || '',
          'postal_code': formData.zip || formData.postal_code || '',
          'country': formData.country || ''
        }
      }
    });
  }
});

// Backup method for older Unbounce implementations
lp.jQuery(function($) {
  $('.lp-pom-form').on('submit', function() {
    setTimeout(function() {
      if (window.location.hash === '#lp-pom-form-success' || $('.lp-pom-form-success').is(':visible')) {
        // Extract form data if the event listener didn't fire
        const formElement = $('.lp-pom-form')[0];
        const formData = new FormData(formElement);
        
        window.dataLayer = window.dataLayer || [];
        window.dataLayer.push({
          'event': 'unbounce_form_submit_backup',
          'user_data': {
            'email_address': formData.get('email') || '',
            'phone_number': formData.get('phone') || '',
            'first_name': formData.get('first_name') || '',
            'last_name': formData.get('last_name') || ''
          }
        });
      }
    }, 1000);
  });
});

Make sure your GTM container is loaded on the Unbounce page by adding the GTM snippet to the “Head Scripts” section.

Step 3: Configure GTM Trigger and Variables

In GTM, create a Custom Event trigger:

Create these Built-In Variables (if not already enabled):

Create these User-Defined Variables for Enhanced Conversions:

  1. Email Variable:

    • Variable Type: Data Layer Variable
    • Data Layer Variable Name: user_data.email_address

  2. Phone Variable:

    • Variable Type: Data Layer Variable
    • Data Layer Variable Name: user_data.phone_number

  3. First Name Variable:

    • Variable Type: Data Layer Variable
    • Data Layer Variable Name: user_data.first_name

Step 4: Create Google Ads Conversion Tag

Create a new tag in GTM:

For Enhanced Conversions, expand “Enhanced Conversions” and set:

Set the trigger to fire on your unbounce_form_submit event.

Step 5: Enable Enhanced Conversions in Google Ads

Back in Google Ads, go to Goals > Conversions and click on your conversion action.

Click “Edit settings” and scroll to “Enhanced conversions”:

This tells Google Ads to expect Enhanced Conversion data from your GTM tags.

Testing & Verification

Preview Mode Testing:

  1. Enable Preview mode in GTM and visit your Unbounce page
  2. Fill out and submit the form
  3. Check that the unbounce_form_submit event fires in the GTM debugger
  4. Verify the Google Ads conversion tag fires with user data populated

Google Ads Verification:

  1. Go to Google Ads > Goals > Conversions
  2. Look for “Recent conversions” - test submissions should appear within 3 hours
  3. Check the “Enhanced conversions” column shows “Receiving enhanced conversions”
  4. Click into the conversion action to see individual conversion details

Cross-Reference Numbers: Compare your Unbounce lead exports with Google Ads conversion counts over a 7-day period. Acceptable variance is 5-15%. Higher variance usually indicates:

Troubleshooting

Problem: GTM debugger shows the event firing but no conversion appears in Google Ads GTM preview mode doesn’t always reflect actual user behavior. Check that your Conversion ID doesn’t include the “AW-” prefix in the GTM tag - it should just be the numbers. Also verify Enhanced Conversions is enabled in Google Ads, not just GTM.

Problem: Enhanced Conversions shows “Not receiving enhanced conversions” despite user data being collected This usually means the email format is wrong or empty. Check your Data Layer Variable is pulling user_data.email_address exactly. Email must be properly formatted (no spaces, valid @ symbol). Phone numbers need country codes for international traffic.

Problem: Conversion count is 2-3x higher than actual form submissions Your conversion action is set to “Every” instead of “One” per click. Go to Google Ads conversion settings and change the count setting. For lead gen, you want “One” conversion per ad click, not per submission event.

Problem: Unbounce form success event isn’t firing consistently Some Unbounce templates don’t trigger the ub-form-success message properly. Use the backup jQuery method in the code above, or switch to tracking via the success URL redirect method. Check if your form has custom success actions that bypass the default event.

Problem: iOS traffic showing much lower conversion rates than Android This is normal post-iOS 14.5, but Enhanced Conversions helps. Make sure you’re collecting email addresses on the form - Google can match these for attribution even when tracking is blocked. Consider implementing Conversions API for Facebook if you’re running cross-platform campaigns.

Problem: Test conversions not appearing in Google Ads after 6+ hours Check if your Google Ads account has conversion delays due to high invalid traffic filtering. B2B accounts with expensive keywords often get delayed reporting. Also verify your GTM container is published (not just previewed) and the live page is firing events correctly.
