Debug UTM Parameters Before Relaunching
Accidents happen: redirects drop query strings, partners rename campaigns, and analytics fills with "(not set)". Use this debugger to rebuild what you expected and share the fixed link.
Need a blank slate instead? UTM Builder remains the master page for generating new links.

FAQ
UTM Debug FAQ
Answers for fixing broken campaign links.
Can I paste URLs with extra parameters?
Yes. Anything after the question mark stays intact so you can review custom fields alongside UTMs.
How do I compare two links?
Open the debugger in two tabs or share a prefilled link via the Share button so stakeholders see the difference.
Does it change the original URL?
No. It never touches live campaigns—use it purely for analysis and documentation.
