UTM means Urchin Tracking Module. In practice, a UTM is a tracking tag you add to a URL so your analytics tool knows exactly which campaign or channel sent a visitor to your website.
UTM is an acronym from the early days of web analytics. It stands for Urchin Tracking Module — named after Urchin Software, the company that first created this tracking system in the late 1990s. Google acquired Urchin in 2005 and used the UTM system as the foundation for Google Analytics.
Today, "UTM" simply means: a set of URL tags used to track where your website traffic comes from. The name Urchin is rarely mentioned — what matters is what UTMs do, not where the acronym came from.
When a marketer says "add a UTM to that link" or "did you UTM-tag the email?", they mean: add tracking parameters to the URL so the analytics tool can tell which campaign drove that traffic.
A UTM-tagged link looks like this:
Everything after "?" is the UTM tracking data. The page loads normally for the visitor — the UTM parameters are silently read by your analytics tool in the background.
Each UTM parameter captures a different piece of information about the traffic:
