Why it matters
Analytics can only tell you a visit came from 'facebook.com' or 'direct'. UTM tags add the detail you actually need: which campaign, which email, which button. Without them, newsletters opened in apps and links in PDFs often show up as direct traffic.
The catch is consistency. 'Newsletter', 'newsletter' and 'news-letter' become three sources in your reports. This builder lowercases values and swaps spaces for hyphens, and its presets use the same names every time. Tagged visits show up in Google Analytics, Plausible, Fathom and quietstats.
How to use it
- Paste the page you're linking to.
- Pick a preset or type the source and medium, then name the campaign.
- Copy the tagged link.
- For many links, paste a CSV below and download the tagged version.
FAQ
Which fields are required?
Source, medium and campaign. Term is for paid search keywords and content tells apart several links in the same message.
Should I tag links on my own site?
No. In some analytics tools a UTM tag starts a new visit, which breaks the record of where people really came from. Tag only links on other sites, in emails, ads and print.
Does it keep my existing query string?
Yes. Existing parameters and any #anchor are kept, and old utm_ values are replaced.
Is anything sent anywhere?
No. The links are built in your browser.
