The External Tracking is referring to any external web page (not built-in CTRwow) that you linked to your website and for which we don’t have any tracking unless we can add the external tracking script.
An example could be the Facebook tracking pixel that you need to place on your web page for Facebook to track it.
The External Tracking option is available on each website Setting tab, as per the picture below:
