If trackExternalLinks is 'true,' linkInternalFilters and linkExternalFilters are used to determine whether any link clicked is an exit link.
|Max Size||Debugger Parameter||Reports Populated||Default Value|
The trackExternalLinks variable should only be set to 'false' if there are no exit links on your site, or if you don't care to track the number of clicks on those exit links. An exit link is any link that takes a visitor off of your site. If trackExternalLinks is 'true,' then when you click an exit link, tracking data is immediately sent. The data that is sent with an exit link includes the link URL, link name, and visitor click map data for that link. If trackExternalLinks is 'false,' then visitor click map data for exit links on your site is likely to be under reported.
The trackExternalLinks variable is expected to be either 'true' or 'false.'
