Frequently asked questions
What is a UTM parameter?
UTM parameters are tags appended to a URL that tell analytics platforms such as Google Analytics exactly where a visitor came from. The five standard parameters are utm_source, utm_medium, utm_campaign, utm_term, and utm_content.
Are UTM parameters case-sensitive?
Yes. Google Analytics treats utm_source=Google and utm_source=google as two separate values, which splits your reporting. Use lowercase and underscores consistently across every campaign link.
Does the UTM Builder store or transmit my URLs?
No. All processing happens entirely in your browser. No URLs, campaign names, or any other data are sent to any server.
