About UTM Bench

Why a campaign link deserves a real tool

UTM tagging looks like string concatenation and is treated as such, which is why so much analytics reporting is quietly wrong. The failures are not dramatic: a capital letter splits one campaign into two rows, an internally tagged banner overwrites the acquisition source, a redirect eats the query string. Nothing errors, the numbers are simply not what they appear to be.

These tools validate as you build rather than after the fact. The builder warns about case and spacing before you publish, the parser audits links somebody else made, and the bulk builder keeps a forty-link campaign consistent because every row comes from one set of values.

Everything runs in your browser

Campaign URLs routinely disclose unlaunched product names, pricing pages and partner relationships. The URLs you build and paste are never transmitted. The only request a page makes after loading is a cookieless page-view count carrying the page's own URL, described on the privacy page.

Built to be fast

Each page is a single request with its styles and code inlined. No web fonts, no framework, no tag manager, and two ad slots below the tool rather than wrapped around it.

How this site is funded

Advertising, placed below the tool rather than around it. The tools themselves stay free, and there is no paid tier that unlocks a feature the free version withholds.

Corrections and bug reports are welcome. If a tool gives a wrong result, that is a bug worth fixing, and a reproducible example is the fastest way to get it fixed. Reach us at hello@utmbench.com.
