Another way of tracking lead source conversions is through WPForms, which is the best and most beginner-friendly WordPress form plugin available.
The WPForms’ User Journey addon allows you to see the steps a user takes before submitting a form, making it effortless to track conversion sources and better understand your visitors.
The addon is available with a WPForms Pro or higher license. After you’ve installed and activated the plugin, go to WPForms » Addons from your WordPress menu.
