You want to check or enable a tag to fire not only on 'view' events (e.g. a page loading) but also 'link' events (e.g. someone clicking on a link).
Ensure you read the AJAX Tracking post before continuing. In a nutshell, Tealium handles calls in two main ways - 'view' and 'link' events. When you load a new page by default a 'view' event is triggered. However, to trigger a 'link' event the utag.link() function needs to be called (or utag.track()). The above post explains how this works.
1. Add the tag you want to check to your profile and save a version if you haven't already : if you don't save, you can't edit the template)
2. Go to 'edit' in the tag configuration >> Advanced Settings >> Edit Template
3. Check the template and amend as necessary
If your template looks like this on line 4 then your tag is only configured to fire on 'view' calls:
You can easily update this to fire on 'link' too as follows:
4. Now just 'Save Profile Template' and then publish to see your tag now being capable of firing on 'link' as well as 'view'
