Fill in the fields below and get a campaign URL with UTM parameters. Empty fields are left out; existing query parameters of the URL are preserved.

The UTM Builder creates trackable campaign URLs by adding UTM parameters to any link, so analytics tools like Google Analytics can attribute traffic to the right source, medium and campaign. It supports the classic tags (utm_source, utm_medium, utm_campaign, utm_term, utm_content), utm_id and the newer GA4 tags.
A UTM parameter is a tag added to a URL (for example utm_source=facebook) that analytics tools read to identify where a visitor came from and which campaign brought them.
utm_source is the only one truly required for tracking. utm_medium and utm_campaign are strongly recommended; utm_term, utm_content, utm_id and the GA4 tags are optional.
Yes. The UTM Builder is completely free and runs entirely in your browser - no sign-up and no data leaves your device.
Paste a ready link and see every UTM tag and query parameter it carries.
