About this tool
URL, campaign, source, medium, term and content become a properly-encoded tracking URL. Existing query parameters on the base URL are preserved.
How to use the UTM Builder tool
- Enter the base URL. Must be absolute, with protocol.
- Add the campaign fields. Any you skip are simply left out.
- Copy the link. URL-encoded correctly for every parameter.
Supported formats
Input
- Plain text or file input
Output
- Converted or analysed output
Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.
Frequently asked questions
Which parameters are set?
utm_campaign, utm_source, utm_medium, utm_term and utm_content, in that order.
Are existing parameters kept?
Yes — the builder parses the URL and appends.
Does capitalisation matter?
Conventionally yes: most teams keep utm values lowercase consistently.
