UTM Link Builder — Campaign URLs, Free
Append campaign-source, medium, name and optional UTM values to a base URL. The builder creates a tagged link; it does not itself collect visits or conversion events.

How to use this tool
Enter a complete URL and the source, medium and campaign values, adding term or content when useful. Existing keys with the same UTM names are overwritten, so review earlier tracking values.
Results and examples
A newsletter link with source=newsletter and medium=email receives those query values. They appear in useful reports only if the destination has the appropriate analytics configuration.
Limitations
- The tool does not enforce an organization-wide campaign naming convention.
- Query values can be exposed outside the site; do not include personal or secret identifiers.
