Copy-ready GA4 link
Keep the original path, query parameters, and #fragment while adding one valid set of UTM tags.
Free UTM builder for GA4 campaign URLs
Add the destination, source, medium, and campaign once. Get a clean GA4-ready URL with every automatic fix explained.

Consistent campaign names
Normalize spaces and letter case so one source does not split into several rows in GA4.
Visible fixes, local processing
See every replaced or normalized value. The destination URL never leaves your browser.
Track each launch channel with the same naming logic
Use utm_source for where traffic came from, utm_medium for the channel type, and utm_campaign for the specific launch. Optional term and content fields separate paid keywords and creative variants.
The same structure works for ads, email, social posts, partners, influencers, and QR codes, so the team can compare channels in one GA4 acquisition report.
Normalize values without hiding the changes
Spaces become hyphens and uppercase letters become lowercase when the recommended toggle is on. Existing UTM tags are replaced instead of duplicated.
Every change appears in the result, and existing non-UTM query parameters plus the #fragment stay in the correct position.
Know what this free UTM builder does not track
The builder accepts http and https destinations and creates one link at a time. It rejects mailto and ftp links, and it does not shorten URLs, count clicks, or run bulk spreadsheet jobs.
Do not add UTM tags to links between pages on your own site because they overwrite the original acquisition source. Test the final link once and confirm it in GA4 realtime reports before launch.
Generate, check, and use the campaign link
Add the landing page, source, medium, and campaign. Use the optional fields only when you need keyword or creative-level attribution.
UTM builder FAQs
Check naming, GA4 compatibility, privacy, and the cases where UTM tags should not be used.
What does UTM stand for?
Urchin Tracking Module — named after Urchin, the analytics company Google acquired before building Google Analytics. In practice it means the five utm_ query parameters that tell GA4 where a visit came from; a UTM maker like this one appends them to your URL correctly.
Why were the UTM parameters already in my URL replaced?
A URL with two sets of UTM tags produces unpredictable attribution, so the builder keeps exactly one set — the values you just entered — and lists the replaced keys in the auto-fix notes so you can double-check.
Do these UTM parameters work with GA4?
Yes. utm_source, utm_medium, utm_campaign, utm_term, and utm_content are the standard parameters GA4 reads for session and traffic acquisition reports, and the same tags are recognized by Google Ads, Mixpanel, Matomo, and most analytics tools.
Should UTM values always be lowercase?
Strongly recommended. UTM values are case-sensitive in GA4, so Google and google are counted as two different sources. Keeping everything lowercase is the simplest convention — that is why the lowercase toggle is on by default.
Is my URL uploaded to a server?
No. The link is built entirely in your browser with no network request, so unlaunched campaign URLs, internal domains, and staging links stay on your machine.
Where should I not use UTM links?
Never tag links that point from one page of your site to another. Clicking an internal UTM link starts a new attributed session and overwrites the real traffic source, corrupting your reports.
