About UTM Builder

UTM parameters tell your analytics where a click came from, so you can measure which channels and campaigns actually drive traffic. UTM Builder on TheToolss adds utm_source, utm_medium, utm_campaign, utm_term, and utm_content to any URL, encoding values safely and skipping the ones you leave blank. Copy the finished link into your ad, email, or social post. Consistent naming keeps your reports clean, so pick conventions and stick to them. Everything runs in your browser — free, private, and no signup.

How to use UTM Builder

  1. Paste the website URL you want to track.
  2. Fill in source, medium, campaign and any optional fields.
  3. Copy the generated campaign URL.

Key features

Frequently asked questions

Which fields are required?
Google recommends at least utm_source, utm_medium, and utm_campaign; term and content are optional.
Should UTM values be lowercase?
It is a good practice — analytics treats Email and email as different values, so pick one style and stay consistent.
Does it work with existing query strings?
Yes. Existing parameters are preserved and the UTM tags are appended correctly.
Is my URL uploaded?
No. The link is built locally in your browser.
