UTM governance

Make the on-spec UTM the easy one to build.

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.

Built for the people who feel the pain

Governance, not just another link builder

Free UTM builders assemble a string. Tagsmith enforces a standard across your whole team — which is the part that actually keeps your data clean.

🔒

Enforced taxonomy

Define the allowed sources, mediums, and a campaign naming pattern. Lock it, and off-spec links are blocked — not just flagged.

🧩

Pattern & rules

Govern campaign structure (region_quarter_initiative_type), require a term for paid mediums, restrict source→medium pairs.

🔍

Audit existing links

Paste the URLs already running and see exactly how much is off-spec, with a compliance score. Clean up the back-catalog.

🧭

Browser extension

Build governed links from any tab, where links are actually born — validated and saved to the shared library in two clicks.

👥

Team workspace

Admins set the spec; everyone builds within it. Invite teammates, manage roles, approve requests, and keep a full audit trail.

📊

Insights

See what your team is actually tagging — top campaigns, sources, creators, and activity over time, in one dashboard.

Why it matters

The hidden tax of UTM chaos

"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."

— the analytics lead

"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."

— the marketing-ops lead
How it works

Set the standard once. Enforce it forever.

1

Define your spec

Set allowed values and a campaign naming pattern. Lock it so it can't drift.

2

Your team builds within it

Everyone builds links in the app or the extension — off-spec links are blocked at the source.

3

Clean data, by default

Every link lands in a shared, audited library. Your analytics finally lines up.

Pricing

The cost of chaos

What dirty UTMs cost you

Ad spend you can't attribute cleanly
$7,500 / mo
That's $90,000 a year of decisions made on bad data. Tagsmith Team is $149/mo.
