Once you are on your click tracking dashboard, hover over the link that you wish to edit and go to the ‘Actions’ button on the right.
Click the ‘Actions’ button and an ‘Edit Link’ link will show up. Clicking on that link will take you to a page where you can easily edit your link.
Your current settings with that link will be pre-populated and you can make changes as you please.
While editing, you can’t change the shortcode. If you want a tracking link with a different custom shortcode, simply create a new tracking link from the click tracking dashboard.
Doesn’t hurt because you’re allowed to create an unlimited number of links.
