Analytics

UTM — UTM Parameters

Tags added to URLs to track the source, medium, and campaign of web traffic in analytics tools.

Definition

UTM (Urchin Tracking Module) parameters are URL tags that pass campaign tracking data into web analytics platforms like Google Analytics. By appending UTM tags to your destination URLs, you can see exactly which campaigns, channels, and content drove traffic and conversions. There are five standard UTM parameters: utm_source (e.g., google, facebook), utm_medium (e.g., cpc, email), utm_campaign (campaign name), utm_term (keyword), and utm_content (differentiates A/B variants). Without UTM tags, traffic from campaigns may appear as direct or (other) in GA, making attribution impossible.

Key Points

  • Five standard parameters: source, medium, campaign, term, content
  • Always use consistent lowercase naming to prevent data fragmentation
  • URL shorteners can hide UTMs in shared links — consider a redirect layer
  • UTM data flows into GA4, HubSpot, Salesforce, and most marketing platforms
  • UTMs work for any channel: paid ads, email, social, influencer campaigns
