Description
UTM Tracker for Contact Form 7 automatically captures UTM parameters from incoming URLs and attaches them to Contact Form 7 submissions.
This allows website owners, marketers, and agencies to see exactly where their leads come from.
If you run marketing campaigns using UTM parameters, the plugin detects them when visitors arrive and stores them in cookies so they can be attached to the form submission later.
Works perfectly even if visitors browse multiple pages before submitting the form.
Perfect for:
• Marketers running Google Ads or Meta Ads campaigns
• Agencies proving campaign ROI to clients
• Businesses tracking lead sources from paid traffic
• Developers implementing attribution tracking in Contact Form 7
Example campaign URL:
https://webfreelancer.in/?utm_source=google&utm_medium=cpc&utm_campaign=spring_sale&utm_id=12345
When a visitor lands on your site with UTM parameters:
- The plugin detects and stores the UTM values in cookies
- Visitors can navigate your website normally
- When they submit a Contact Form 7 form, the UTM data is automatically included in the email notification
This helps you understand which campaigns generate real leads.
The plugin is lightweight, privacy-friendly, and optimized for performance.
