Free UTM Link Builder
Enter a page address and your campaign details and get a tagged link for analytics, checked for common mistakes.
Free, with no sign-up. Fair-use limits apply. To enforce them we keep the domain you enter and a scrambled form of your IP address for 30 days, as described in our privacy policy.
What UTM parameters do
UTM parameters are labels added to a link so that analytics can tell which campaign, channel or advert sent a visitor. They only work if you name things consistently, because Email and email are counted separately.
How to use it
Enter the landing page, then source, medium and campaign. Term and content are optional. Press Build link and copy the result. The builder lower-cases values, replaces spaces and warns about characters that cause trouble.
Habits that keep reports clean
- Use lower case and hyphens, never spaces.
- Decide one name per source and stick to it.
- Do not use UTM tags on links inside your own site, because they overwrite the real source.
Frequently asked questions
Do UTM tags affect SEO?
Not directly, but tagged URLs can be indexed as duplicates. Use canonical tags so that they are not.
Are the parameters case sensitive?
Yes in most analytics tools, which is why consistent lower case matters.
Is my link stored?
No, the link is built and shown, and not kept.
