When tracking links you often use tracking parameters that get added to urls when you export out of Taxi.
Another way of tracking links is by adding attributes to the <a> tags in your HTML. For example, you might add something like alias = "hero image" to the anchor tags to track how many times someone clicks a certain link in an email.
Attributes like these can be added in Taxi link tracking profiles through Attribute Settings.
When you export, any attributes that you add here will be automatically added to all editable links in your email.
Anything that you can do with liquid in the href settings can also be done in attribute settings. Here is more information on this: Link Tracking Manager - href settings
For example, you can exclude certain links from getting these attributes when exporting, or you can automate the value that's added based on the module name.
