Your campaign link
Existing query parameters and the fragment are preserved; UTM values are replaced. Labels use lowercase and underscores. Keep personal information and secrets out of labels, and test the destination before sharing.
How to use this tool
- Paste the complete destination URL, including any existing query parameters.
- Use stable source, medium, and campaign names; optionally identify a creative variant.
- Copy the link and test the destination before distribution.
A worked example
Source “LinkedIn” and campaign “Autumn launch” become utm_source=linkedin and utm_campaign=autumn_launch. Existing ref=partner remains intact.
Use the prefilled example to explore the output, then replace it with your own inputs. Review dates and responsibilities with your team before using the result.
Common questions
Can I include customer names in UTMs?
Avoid personal information and secrets. Campaign values travel in URLs and may appear in analytics, logs, screenshots, and shared links.
