When you create a link using the Link Builder, you have the option to track each time the link is clicked. Clicks are tracked in the Control Panel > Communications Tab > Setup > Link Tracking.
The grid shows all links where tracking is enabled, where the link is (an email or custom page), what the link is to (an event, document, etc.), and the click data.
To see where the link points to, click the View (eye) icon. To temporarily disable tracking, click the Disable (stop) icon. To delete the tracked link and its data, click the Delete icon.
If you want to begin tracking a link after you've disabled it, click the Enable icon.
