One governed naming convention your whole team builds against — so campaigns stop fragmenting and your analytics finally adds up. Governance where links are made, and an audit to catch the ones that slip through.
Free UTM builders assemble a string. Tagsmith enforces a standard across your whole team — which is the part that actually keeps your data clean.
Define the allowed sources, mediums, and a campaign naming pattern. Lock it, and off-spec links are blocked — not just flagged.
Govern campaign structure (region_quarter_initiative_type), require a term for paid mediums, restrict source→medium pairs.
Paste the URLs already running and see exactly how much is off-spec, with a compliance score. Clean up the back-catalog.
Build governed links from any tab, where links are actually born — validated and saved to the shared library in two clicks.
Admins set the spec; everyone builds within it. Invite teammates, manage roles, approve requests, and keep a full audit trail.
See what your team is actually tagging — top campaigns, sources, creators, and activity over time, in one dashboard.
"At quarter-end I find out that Email, email, and eml are three rows in GA4 — and the board deck is wrong. Lowercase-forcing alone kills a whole class of my problems."
"I've bought beautiful tools that died at 20% adoption. The one that works lives where the work happens — a browser extension, not another tab to remember."
Set allowed values and a campaign naming pattern. Lock it so it can't drift.
Everyone builds links in the app or the extension — off-spec links are blocked at the source.
Every link lands in a shared, audited library. Your analytics finally lines up.
Governance only works when your whole team is on it — so we never charge you more for adding people.
A rough estimate of the ad spend you can't trust because attribution is fragmented.
