What are UTM Parameters & Why are they Critical?
UTM (Urchin Tracking Module) codes are standard query parameters added to a website URL to track the effectiveness of marketing campaigns across diverse traffic sources and referral channels.
When a user clicks a UTM-tagged link, web analytics suites (like Google Analytics, Plausible, or Mixpanel) parse the parameters to accurately classify where the traffic originated, what creative or medium drove the engagement, and which specific campaign copy triggered the action.
