Frequently Asked Questions
What are UTM parameters?
UTM parameters are tags appended to URLs that tell analytics tools where traffic came from — source, medium, campaign name, and optional term and content values.
Which UTM fields are required?
At minimum, use utm_source, utm_medium, and utm_campaign. Google recommends all three for consistent campaign tracking in Analytics.
Should I use spaces in UTM values?
No. Use underscores or hyphens instead of spaces. This tool URL-encodes values automatically so special characters are safe in links.
Do UTM links affect SEO?
UTM parameters create technically different URLs. Use canonical tags — try the Canonical Tag Generator — to consolidate signals on the preferred URL.
Is this tool free and does it work on mobile?
Yes on both counts. The UTM Link Builder on draft21 is completely free with no sign-up required and works on all devices.
