UTM builder for marketing teams
Clean campaign data starts with links your team can't get wrong.
Free UTM builders let anyone type LinkedIn, linkedin and li into the same field — and invented mediums like newsletter push traffic into GA4's Unassigned channel. Tagline lets an admin define the allowed values once; everyone else can only build links inside those rules.
The demo skips sign-in and opens a sandbox with the example taxonomy, three templates and 20 example links. Nothing you do there is saved to a database.
Without rules
- utm_source=LinkedIn&utm_medium=newsletter
- utm_source=linked-in&utm_medium=Paid Social
- utm_source=li&utm_medium=qr
- utm_campaign=Q1 Launch!!
Four rows in GA4 for one channel, and traffic in Unassigned.
With Tagline
- utm_source=linkedin&utm_medium=paid-social
- utm_source=linkedin&utm_medium=social
- utm_campaign=q1-2026_enterprise_buyers-guide
Dropdowns for sources and mediums, allowed pairs only, campaign names from a template, free text auto-formatted as you type.
Guardrails, not guidelines
Admins set sources, mediums, allowed pairs and the campaign template. Members just build links.
Safe URL handling
Existing query strings and #fragments survive, and duplicate utm_ values are replaced rather than stacked.
A shared link log
Every link is searchable with filters, per-row QR codes and CSV export — and you're warned about exact duplicates.
