New user here, so my apologies in advance if this is an old question. (I couldn’t find any promising answers by searching the forums or FAQ.)
On one of my domains, most of the visits are listed as having a duration of “0s” (zero seconds). How exactly is this determined, and what does it mean? Does it mean an actual human user clicked on a link, but hit “Back” less than a second later? Does it mean the visitor was a spider or other robot? Or does it mean something else entirely?
