ReferAll is a lightweight yet powerful referral tracking system for WordPress. It allows you to create “Associates” and track visitors who land on your site using their unique referral links.
The plugin features deep integration with Elementor, allowing you to: 
* Display associate-specific content like names and logos. 
* Automatically hide or show any Elementor element (widgets, sections, containers) based on whether a referral cookie is present. 
* Use dynamic tags like <code>%ref_name%</code> and <code>%ref_id%</code> within custom Elementor widgets.
It also integrates with Contact Form 7 to capture the referral ID in form submissions.
