Glossary

UTM Source

The UTM source identifies where traffic comes from, such as google, newsletter, linkedin, or partner-site.

What UTM Source means

Use this glossary page to understand the term and link to practical campaign tracking tools.

Use consistent lowercase naming so reports do not split the same campaign into multiple rows.
Validate links before launch to catch missing source, medium, campaign, broken redirects, and encoding issues.
Document examples for your team so agencies, creators, paid media, and email teams follow the same pattern.
Review campaign reports after launch and refine naming conventions before the next promotion.

Recommended workflow

Start with a clear destination URL, choose lowercase campaign values, keep source and medium consistent, validate the final link, and document the naming pattern before publishing.
