UTM Builder
Build campaign URLs with UTM parameters and keep a historyHalf your traffic shows up in analytics as a mystery. UTM parameters end that: short tags on your URL telling GA4 exactly which post, email or ad sent each visitor. Build them correctly every time, in seconds.

About the UTM Builder
Without UTM tags, a click from your best performing post and a click from a random mention both land in your analytics as undifferentiated traffic. This free builder creates clean, correctly encoded campaign URLs: it validates the base URL, merges parameters with existing query strings, and normalizes values to lowercase.
Every link you build is saved to a local history in your browser, so repeat campaigns are fast: last month's newsletter link is one click away. No account, no server storage, just a focused tool for marketers.
Where it helps most
The campaigns where clean tagging turns mystery traffic into answers.
Track social posts
For anyone running social posts alongside GA4, clean tagging turns campaign work from a skipped chore into a ten-second habit.
Measure email sends
Tag every newsletter and email campaign link so each send's true performance shows up clearly in your daily GA4 reports.
Split ad variants
Add the optional term and content fields when you need to distinguish paid keywords or compare ad variants side by side.
Reuse past links
Every link you build is saved to a local history, so last month's newsletter URL is one click away for the next send.
Tagging without the mess
Conventions that keep your reports reconcilable.
Keep case consistent
Letter case splits reports: GA4 treats Facebook and facebook as two different sources, so keep one lowercase convention with no spaces.
Fill the big three
Source, medium and campaign are the three fields every tracked link needs: where traffic comes from, how it arrives, and which effort it belongs to.
Skip internal links
Never add UTM tags to links inside your own website; they overwrite the visitor's original campaign attribution in GA4 and corrupt your data.
UTM Builder: private by design
Nothing is uploaded to a server and no account is needed. Your link history lives in your own browser's local storage.
UTM Builder FAQs
Source, medium and campaign. Source is where the traffic comes from, like facebook or newsletter. Medium is how it arrives, like social or email. Campaign names the effort, like spring_sale. Term and content are optional extras for paid keywords and ad variants.
