Webflow Forms Attribution Tracking
Finally know which marketing channels fill your Webflow forms. AttributionHub captures UTM parameters, referrers, and landing pages — and handles Webflow's unique fetch-based form submissions automatically.
The Webflow Form Tracking Challenge
Webflow is a fantastic platform for building marketing sites that look professional without writing code. Its built-in form feature is convenient for capturing leads. But there's a catch that trips up most analytics setups.
Webflow forms submit via JavaScript fetch() instead of traditional HTML
form submissions. This means the page never reloads, and many tracking
tools that rely on page navigation events miss the conversion entirely.
On top of that, Webflow doesn't offer a straightforward way to add hidden fields through the visual designer. You can add them via embed elements, but the tracking piece still needs to handle the fetch-based submission.
AttributionHub is built to handle both of these Webflow-specific quirks. It detects Webflow forms, populates hidden fields, and tracks conversions through Webflow's unique submission flow.
What Data Gets Captured
UTM Parameters
Source, medium, campaign, term, and content — captured from URLs and stored with each Webflow form submission.
Landing Page & Referrer
The visitor's entry page and referring website, so you understand the full path from click to form submission.
Channel Classification
Each lead is automatically tagged with its channel: Paid Search, Organic, Social, Direct, Email, or Referral.
First Touch & Last Touch
Track the original discovery source and the most recent touchpoint before conversion, across multiple sessions.
How It Works
Webflow forms render as standard HTML but submit via fetch instead of a page redirect. AttributionHub handles both field population and conversion tracking for this behavior.

Use Cases

SaaS Landing Pages — Webflow is popular for SaaS marketing sites. Know which ad campaigns drive demo requests and signups through your Webflow forms.
Freelancers & Consultants — If your Webflow site has a contact or project inquiry form, attribution tracking shows you exactly where clients discover your work.
Directory & Marketplace Sites — For Webflow-built directories with submission forms, track which traffic sources bring the most listings or inquiries.
