UTM Builder
Build UTM-tagged URLs for Google Analytics campaign tracking.
How to Use
- Enter your destination URL (e.g. https://example.com/landing).
- Fill in Source, Medium, and Campaign name (required).
- Optionally add Term and Content for more granular tracking.
- Copy the generated URL and paste it into your ad or email.
When to Use This
- Tagging the links in a newsletter so the email channel shows up separately from organic traffic in the analytics report.
- Distinguishing two creatives in the same paid campaign through utm_content, so the weaker ad can be identified and cut.
- Handing an agency a tagged URL for a placement, so their traffic is attributed correctly without you editing the report afterwards.
- Rebuilding a tagged link someone truncated when pasting it into a social post, with the parameter names spelled the way analytics expects.
Frequently Asked Questions
About This Tool
UTM parameters are ordinary query string parameters that an analytics tool reads when a visitor lands on a page. They describe where the click came from: utm_source names the referrer, utm_medium the channel, utm_campaign the effort, with utm_term and utm_content for keyword and creative. Nothing happens server-side, the values are carried in the URL and recorded by the analytics script, which is also why they are visible to anyone looking at the address bar.
This builder requires a URL, source, medium and campaign, and adds term and content when supplied. Spaces become underscores and values are lowercased, except in utm_term, where spaces become plus signs. Encoding is handled by URLSearchParams. The link is rebuilt as you type, and a missing required field is named in the status line.
Notes & Limits
- A trailing slash is stripped and a question mark is appended, so a destination that already has a query string or a fragment comes out malformed.
- Values are lowercased for you, which keeps reports tidy but means a source you deliberately capitalized will not match history recorded with capitals.
- Nothing checks that the destination exists or that your analytics property is configured to read these parameters. The tool only assembles a string.
- Tagged links are public. Anyone can copy one, so a campaign name that appears in a URL should not reveal anything you would not publish.
