UTM Parameters: The Complete Guide to Campaign Tracking
2026-04-28 7 min read
Stop flying blind with your marketing campaigns. Learn exactly how UTM parameters work, when to use each one, and how to build clean UTM links with our free UTM builder.
UTM parameters are query string tags you add to URLs to track where your website traffic comes from. Without them, Google Analytics shows everything as "Direct" or "Unknown."
The 5 UTM Parameters
- utm_source: Where the traffic comes from (google, newsletter, twitter)
- utm_medium: The marketing channel (cpc, email, social, organic)
- utm_campaign: The specific campaign name (summer_sale_2026)
- utm_term: Keywords for paid ads (used in Google Ads)
- utm_content: Differentiates ads or links (banner_v1 vs banner_v2)
UTM Best Practices
- Always use lowercase — UTM params are case-sensitive in some analytics tools
- Use hyphens instead of spaces (utm_campaign=black-friday not black friday)
- Be consistent with naming — create a spreadsheet/naming convention
- Never use UTMs on internal links — it resets session attribution
