Webflow form customization: Track UTM parameters
Jak
UTM Tracking System to Capture Lead Sources Automatically
Capture UTM data from the URL and store it in hidden form fields. The data stays saved even if users leave and return, helping track lead sources.
What This System Does
It captures UTM parameters from the URL and stores them in hidden fields inside an Webflow form so lead sources are always recorded.
How It Works Behind the Scenes
A script reads the UTM values, saves them in local storage, and auto-fills the hidden form fields even if the user comes back later.
Why Businesses Use It
Companies like RCC can track exactly where each lead came from. Google ads, Facebook, email campaigns. All mapped directly in their form submissions.
Built for Reuse
The setup is created as a reusable component so it can be added to multiple forms without rebuilding everything each time.
