About the UTM Link Builder

UTM parameters tell analytics tools where visitors came from. Fill in source, medium and campaign (and optionally term, content and id) to generate a correctly encoded tracking link. Existing query parameters on your URL are preserved.

How to use it

  1. Enter the landing page URL.
  2. Fill in the campaign fields.
  3. Copy the tagged URL.

Good to know

  • Never put personal data (emails, names) in UTM parameters.
  • Don't use UTMs on internal links — they overwrite the original traffic source.

Frequently asked questions

Are UTM values case-sensitive?

Yes. Use consistent lowercase naming to avoid split reports.

Which fields are required?

Source, medium and campaign are the minimum for reliable reporting.
