Link Alias - gives each link to be tracked a special name. Aliases can be used to differentiate between two different links that go to the same URL. Each link in this case would be given a different alias. Aliases can also be used to group different links together into a larger group to measure the overall number of clicks in a message. In this case all the links would be given the same alias. If aliases are not defined for tracked links (which is possible, since aliases are optional), LISTSERV Maestro will only be able to find the URL of the link in the tracking data.
