UTM Parameters
Five standard tags appended to a URL that record where a link was placed, in what format, and as part of which campaign.
Analogy Mental model
A unique serial number printed on every flyer you hand out. When a customer arrives with one, the till staff know exactly which batch, which street, and which promotion brought them in.
In practice What you actually do
Use a URL builder rather than typing tags by hand, and apply them to press mentions, social bios, newsletter links, and directory buttons. Keep a shared naming sheet so campaign names match across teams. Note that some AI assistants append their own source tag automatically when citing a page.
Where people get burned Pitfalls
Never put UTM parameters on internal links. Doing so ends the existing session and starts a new one attributed to your own tag, which destroys the attribution for the whole visit and is very difficult to unwind once it is in a template.
