UTM Parameters: The Complete Guide to Campaign Tracking in Google Analytics

The Attribution Problem

You run email campaigns, post on social media, run Google Ads, and publish blog content. Traffic comes in. Conversions happen. But which channel actually drove the sale? Without UTM parameters, you cannot know.

What Are UTM Parameters?

UTM (Urchin Tracking Module) parameters are tags appended to URLs that tell analytics platforms exactly where traffic comes from:

https://example.com/landing-page
  ?utm_source=newsletter
  &utm_medium=email
  &utm_campaign=spring-sale-2025
  &utm_content=hero-cta-button

The Five UTM Parameters

utm_source (Required)

The origin of the traffic: google, newsletter, facebook, linkedin

utm_medium (Required)

The marketing channel: cpc, email, social, paid-social, referral, affiliate

utm_campaign (Required)

The specific campaign: spring-sale-2025, onboarding-sequence, product-launch-v2

utm_content (Optional)

Differentiates multiple links in the same campaign: hero-cta-button, sidebar-banner, text-link

utm_term (Optional)

Used for paid search to identify the triggering keyword.

UTM Naming Conventions

UTM parameters are case-sensitive. utm_source=Facebook and utm_source=facebook appear as TWO different sources.

Real-World Examples

Email Marketing:

https://example.com/pricing
  ?utm_source=klaviyo&utm_medium=email
  &utm_campaign=cart-abandonment&utm_content=email-3-cta

Paid Social:

https://example.com/landing
  ?utm_source=facebook&utm_medium=paid-social
  &utm_campaign=summer-2025&utm_content=video-ad

---

Always Tag These Channels

• All email marketing links
• Paid search (Google Ads, Bing Ads)
• Paid social (Facebook, Instagram, LinkedIn, TikTok Ads)
• Newsletter sponsorships and partnerships
• QR codes (offline tracking)

Never tag internal links — UTM parameters on internal links break session attribution.
