- The 5 UTM Parameters
- UTM Naming Conventions
- UTM Best Practices
UTM parameters are tags added to URLs that tell Google Analytics where a visitor came from, which campaign drove them, and which specific link they clicked. Without UTMs, traffic from email, social media, and paid campaigns appears as "direct" or "referral" — making attribution impossible.
The 5 UTM Parameters
utm_source (where the traffic comes from: google, facebook, newsletter), utm_medium (how it was delivered: cpc, email, social), utm_campaign (campaign name: spring-sale-2025), utm_term (keyword, for search ads), utm_content (differentiates multiple links in the same campaign: banner-top vs. button-cta).
UTM Naming Conventions
Consistency is critical. Decide on lowercase-with-hyphens vs. underscore format (lowercase hyphens recommended). Define standard values for common sources and mediums. Document your naming convention in a shared spreadsheet and require all team members to use it. Inconsistent UTMs produce fragmented, misleading data.
UTM Best Practices
Tag every link in emails and social posts. Use the Google Campaign URL Builder for error-free URL creation. Never use UTMs on internal links (this breaks session attribution). Shorten UTM-tagged URLs with Bitly or native platform shorteners before sharing publicly.
