UTM Builder
Add campaign parameters to a URL so you can see which email, ad, or post sent the visit.
Use lowercase and hyphens. Do not put secrets in UTM values. This builder does not shorten links or track clicks.
Label the click
Source, medium, and campaign are the three fields you should keep consistent. The builder refuses junk that is not an http(s) URL.
FAQ
Will UTM tags help me rank?
No. They label a click for analytics. They are not an SEO ranking lever.
