DTM Debugger displays 'SATELLITE: Rule "Linker link" fired', even though the rule is not available in the DTM UI.
If the Google Analytics tool is present within the DTM web property and a click event occurs on an anchor tag, Dynamic Tag Manager automatically inserts an event-based rule called "Linker link". This rule is invisible and is not available in the UI.
In the DTM property's library, the following is the code specific to the rule:
{"name":"Linker link","event":"click","trigger":[{"engine":"ga","command":"link"}],"selector":"a","conditions":[function(event,target){ return _satellite.isLinkerLink(this) }
