UTM Builder

What UTM parameters do

UTM parameters are tags added to a URL's query string that tell analytics tools (Google Analytics, GA4, most marketing platforms) where a visit came from. utm_source identifies the referrer (e.g. newsletter, twitter), utm_medium the channel type (e.g. email, cpc, social), and utm_campaign the specific push (e.g. summer_launch). utm_term and utm_content are optional and mainly used to distinguish keywords or ad variants within the same campaign.

Frequently asked questions

Do UTM parameters affect SEO or page functionality?

No — they're purely for analytics tracking. Search engines generally canonicalize them away, and most sites ignore unknown query parameters entirely, so adding them doesn't change how the page behaves.

Why keep names lowercase and consistent?

Most analytics tools treat UTM values as case-sensitive strings, so Email, email and e-mail would show up as three separate sources in your reports instead of one — consistent lowercase naming keeps your data usable.

Is my URL sent anywhere?

No — the URL is only assembled in your browser using JavaScript; nothing is uploaded or logged.
