Step 1: Enable Required Built-In Variables
Enable the built-in variables “Click URL” and “Click Text” (if not already enabled). GTM will need access to these variables to determine the target URL of the link that was clicked.
Step 2: Set-Up Trigger
Create a trigger called “outbound link click”. This trigger is intended to fire when a user clicks an outbound link.
A key question is: how do you determine if the link is an outbound link?
