UTM tracking for Webflow Forms
Capture marketing attribution data in every Webflow Forms submission.
The problem
Webflow Forms captures what people type into your forms, but not how they found you. You're missing the marketing data that tells you which channels actually drive leads.
How to set it up
Add hidden fields to your Webflow Forms forms. SourceTag's script finds those fields and populates them with attribution data when a visitor submits. Channel, source, campaign, click IDs, and landing page all flow through automatically.
Install SourceTag on your site
Add the SourceTag script tag to your site header.
Add hidden fields to your Webflow Forms form
In Webflow Forms, add hidden fields named st_fc_channel, st_fc_detail_1, st_fc_detail_2, etc. See the full field list in your SourceTag dashboard.
Submit a test form
Visit your site with ?utm_source=test&utm_medium=cpc and submit a form. Check the submission for attribution data.
