Event Category

An event category is a grouping label that gathers related events under one heading, so a long event list becomes browsable and analyzable at a higher level.

An event category becomes meaningful once the number of events passes a threshold and a flat list is no longer comprehensible; categorizing takes those events into groups like “navigation,” “commerce” or “account,” so they can be found and a whole area's performance seen at once. This idea is part of event taxonomy and should not be conflated with an event name: a name defines one specific event, a category places several events together. The common trap is arbitrary, shifting categorization; without a clear rule for which category each event belongs to, two people put one event in two categories and the grouping brings ambiguity instead of clarity. A good category set is small, non-overlapping and documented.
