The problem
Someone fills out a form on your Webflow site. You know they did it, but not why. Was it your Google Ads? An organic search? A referral? Webflow doesn't track this, so you're left guessing which marketing is working.
How to set it up
Install SourceTag on your Webflow site via Project Settings > Custom Code > Head Code. It tracks how visitors arrive, stores attribution data in a cookie, and writes it into hidden form fields when someone submits. The data flows wherever your form sends it.
Copy your script tag
From the SourceTag dashboard, copy the one-line script tag for your site.
Add to Webflow
In Webflow, go to Project Settings > Custom Code > Head Code and paste the script tag.
Add hidden fields to your forms
Add hidden fields to your forms for the SourceTag data. See your form builder's setup guide.
Test
Visit your site with UTM parameters and submit a form to verify.
Compatible form builders
