About UTM Parameters

What are UTMs?

UTM stands for Urchin Tracking Module. These are tags appended to URLs that let analytics tools like GA4 identify where your traffic comes from — which campaign, source, or medium drove a visit.

Required vs Optional

utm_source, utm_medium, and utm_campaign are required for GA4 to attribute traffic correctly. utm_term is for paid keywords, and utm_content helps A/B test ad creatives pointing to the same URL.

Naming Best Practices

Always use lowercase and underscores. Avoid spaces and special characters. Consistency is key — "Email" and "email" appear as separate rows in GA4 reports, silently splitting your campaign data.

Privacy Note

This tool runs entirely in your browser. No URLs or campaign data are ever sent to any server. History is stored in your browser's localStorage only and never leaves your device.
