Definition

UTM parameters are tags appended to URLs (utm_source, utm_medium, utm_campaign, etc.) so analytics tools attribute traffic and conversions to specific campaigns.

Detailed Explanation

Standard parameters:

  • utm_source — platform (google, facebook, newsletter)
  • utm_medium — channel type (cpc, email, social)
  • utm_campaign — campaign name
  • utm_content — ad variant (optional)
  • utm_term — keyword (optional)

Use lowercase, consistent naming. Document conventions in a shared spreadsheet.

Nepal Context

Agencies running multi-client campaigns need strict UTM conventions — mixed naming breaks GA4 reports. Use utm_source=facebook&utm_medium=paid_social&utm_campaign=dashain_2026.

Key Takeaways

  • Required for accurate GA4 campaign reporting
  • Consistent naming convention across team
  • Auto-tagging handles Google Ads; UTMs needed for everything else

Common Mistakes

  1. Inconsistent campaign naming (Dashain2026 vs dashain-2026)
  2. Changing UTMs mid-campaign (breaks historical comparison)
  3. Forgetting UTMs on email and social bio links
