UTM builder

Paste a URL, fill in your campaign details, copy a clean tracking link. Handles existing query strings automatically.

Build your link

Required fields are marked with *.

Your tracking URL

Fill in URL, source, medium and campaign to generate your tracking URL.

How it works:

  • If your URL already has a ?, parameters are joined with &.
  • If it doesn't, they're added after a fresh ?.
  • Values are URL-encoded automatically — spaces, punctuation, emoji all safe.
  • Fragments (#section) are kept at the end where they belong.

Inside MoleculeData

One clean link is a start. Now audit the other 4,712.

A single tracking URL is easy. Keeping every paid URL across Meta, Google, TikTok and Snapchat clean — without a spreadsheet — is the hard part. The MoleculeData UTM health check does it for you.

  • Per-platform health score — see exactly which channels are leaking attribution, in one glance.
  • Templates that fit each platform — Google's {campaignid}, Meta's {{campaign.name}}, TikTok's __CAMPAIGN_NAME__ — copy, paste, done.
  • Drill into every campaign — filter by platform, account, valid or invalid; fix the offenders in minutes.
