Google Ads Tracking for WordPress Forms

Google Ads conversion tracking for WordPress contact forms

Goal:

Fire a Google Ads lead conversion on successful form submit.

Capture and submit ad click IDs: gclid + iOS fallbacks wbraid / gbraid (persist ~90 days).

Populate hidden fields on our forms and pass values into CRM.

Stack / Context:

WordPress (Avada theme). Form is standard WP form plugin or HTML (you can advise).

We’re not asking for GA4 events—Ads only.

Scope:

Add a lightweight site-wide (or landing+form pages) script or GTM equivalent to store gclid/wbraid/gbraid in 1st-party cookies and auto-fill hidden inputs.

Add hidden inputs to the forms (gclid, wbraid, gbraid) and confirm they reach the submission payload/CRM.

Configure a Google Ads Conversion tag in GTM using our AW ID + Label, triggered by thank-you page or a custom event on submit.

(Optional) Enable Enhanced Conversions for Leads (email/phone mapping).

Deliverables:

GTM container export or code snippet + clear install steps.

Acceptance tests:

Using test URLs (?gclid=TEST123), IDs persist and appear in the form payload.

Ads conversion tag fires (GTM Preview) on submit/thank-you.
