We'll create fresh WordPress site with UTMs Carry Pages installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Capturing all the UTM variables when user land on your website, this plugin will add all the UTM parameters (accepted only the most used UTMS: utm_source, utm_medium, utm_term, utm_content, utm_campaign). Links with tel: or mailto: will be ignored. External links will carry UTMs too.
