Root Cause: Enhanced Conversions for Leads Was OFF

Setting Identified

In the Transporters.io backend, the "Enable Enhanced Conversions for Leads Data Layer" checkbox was unchecked. This setting pushes customer data (email, phone) into the dataLayer so Google Tag Manager can use it for Enhanced Conversions for Leads attribution.

1

Quote Form Conversion (Google Ads Tag)

Fires when someone submits the form on buscharter.com.au. Without Enhanced Conversions for Leads enabled, it could only attribute conversions using the Google Click ID (GCLID) and cookies. If the cookie was lost, blocked, or the user switched devices, the conversion was missed.

2

Transporters.io Lead Data (Offline Upload)

Uploads lead data from the Transporters backend (including email and phone) back to Google Ads. Because it sends first-party customer data directly, Google can match more conversions back to the original click, even when cookies are missing.

3

The Gap Explained

The 7% gap (43 extra conversions in Transporters) represents leads where Google's tag couldn't attribute the form submission to an ad click (due to missing cookie/GCLID), but the offline upload successfully matched it using email/phone data. Transporters was doing a better job of attribution than the tag itself.

What Happens Now

With "Enhanced Conversions for Leads Data Layer" now enabled, the Quote Form tag will push customer data (email, phone) into the dataLayer. Google Tag Manager will use this to match more conversions back to ad clicks. Expect the Quote Form numbers to align more closely with (or exceed) Transporters.io over the coming weeks, as both sources will now have first-party data for matching. Monitor this gap weekly to confirm convergence.
