UTM source vs medium vs campaign: how to name each one without confusion

UTM confusion usually starts because source, medium, and campaign sound similar when a team is moving fast. In practice they work best when each one answers a different question. Source says where the click came from. Medium says what type of channel it was. Campaign says which initiative or promotion that click belonged to.

The reporting problems come when teams collapse those roles into one field. If source sometimes means platform, sometimes campaign, and sometimes audience, the dashboard becomes harder to interpret every month. A simple naming rule prevents a surprising amount of downstream cleanup.

The easiest way to keep the fields distinct is to decide them in the same order every time: platform first, channel second, campaign third. That small habit makes new tracking links easier to create and old reports easier to compare.
