I am using Google Tag Manager and Google Analytics to track events for downloads from my site. I am then using an event tracking Goal based on the "Download" category. The number of events in the "Download" category is ~2X the number of goals being tracked. Does this indicate an issue with either the events or the goal set up, or is this expected and why?
GA will track any goal conversion once per visit. It won't count repeat goal conversions per session. Hence, people could download multiple files (thereby triggering multiple download events, but only one goal conversion). If the event action is subdivided into several event actions and/or event labels, you will see more unique events than goal conversions. Use event action/label as a secondary dimension in the event reports to see if this holds true.
For exmaple: Consider two events with
Event 1: EC: Download EA: FileA
Event 2: EC: Download EA: FileB
would result in one goal conversion for download, but two unqiue events.
