Free UTM Builder – Create Campaign URLs for Google Analytics

How This UTM Builder Works

Paste the landing page URL you are promoting, fill in utm_source, utm_medium and utm_campaign, then copy the tagged link. Empty fields are left out, and query parameters or #anchors already in your URL are kept. For example:

https://example.com/pricing?plan=pro#faq

becomes

https://example.com/pricing?plan=pro&utm_source=newsletter&utm_medium=email&utm_campaign=2026-10_launch#faq

Values are URL-encoded for you, so a space becomes +. Hyphens and lowercase values keep reports easier to read. If your URL already contains a UTM parameter you also fill in here, the value you enter replaces it.

Which UTM Fields Do You Need?

• Source, medium and campaign belong on every tagged link. Google Analytics shows missing values as (not set).
• Content tells two links or ad creatives in the same campaign apart, such as a header and a footer button.
• Term is meant for paid search keywords and can usually stay empty.

This builder has fields for those five parameters. GA4 also accepts utm_id and utm_source_platform; if you use them, add them to the destination URL and the builder keeps them.

UTM Generator, Builder or Creator?

They are different names for the same job: adding UTM parameters to a URL. This campaign URL builder runs entirely in your browser and works with Google Analytics 4 and other analytics tools that read UTM parameters.
