How does this tool work?
This builder adds UTM parameters to a destination URL so that visits from a newsletter, a social post or an ad are credited to the right source in Google Analytics, Matomo or any tool that reads these parameters. It keeps existing parameters and encodes every value correctly.
The destination URL must be an absolute http or https address; otherwise an error message appears.
The five fields fill in utm_source, utm_medium, utm_campaign, utm_term and utm_content. Leading and trailing spaces are removed and each value is encoded (a space becomes +).
An empty field removes the corresponding UTM parameter if it was already in the URL; a filled field replaces the old value instead of creating a duplicate.
The URL’s other parameters, such as ?ref=home, and any fragment are kept; the UTM parameters are added after them in a fixed order.
How to use this tool
Paste the destination URL
The exact address of the target page, with https://.
Fill in source, medium and campaign
For example newsletter, email and summer-sale-2026.
Add term and content if useful
The term for a paid keyword, the content to tell apart two links in the same message.
Copy the generated URL
Use it as it is in your email, post or ad.
Use cases
Measure a social campaign
Compare visits from the same post shared on LinkedIn, Facebook and Instagram.
Track a QR code or printed material
Find out how many visits come from a poster or brochure by encoding a UTM URL in the QR code.
Examples
Newsletter button
The existing ref parameter is kept and the four UTM parameters are added after it; utm_term, left empty, does not appear.
Input
Destination URL: https://example.com/sale?ref=home
Source (utm_source): newsletter
Medium (utm_medium): email
Campaign (utm_campaign): summer-sale-2026
Content (optional): main-buttonResult
Generated UTM URL: https://example.com/sale?ref=home&utm_source=newsletter&utm_medium=email&utm_campaign=summer-sale-2026&utm_content=main-buttonTips and best practices
- Write values in lower case without spaces: Google Analytics treats Newsletter and newsletter as different, which scatters your data.
- Keep one convention for the whole team (email, not e-mail or mail) and record it in a shared sheet.
- Never use UTM parameters on your site’s internal links: they overwrite the visit’s real source and distort attribution.
- In GA4, pick utm_medium from the recognised values (email, social, cpc, referral…) so visits land in the right channel group.

Frequently asked questions
Which UTM parameters are required?
The tool does not force any, but utm_source, utm_medium and utm_campaign are the three that analytics tools expect to attribute a visit correctly. utm_term and utm_content are optional.
What if the URL already contains UTM parameters?
Each filled field replaces the existing value and each empty field removes the parameter, so you get a URL without duplicates that matches the form.
Do UTM parameters hurt SEO?
No, as long as you keep them for external links. If URLs with UTM parameters get shared and crawled, a canonical tag pointing to the clean URL avoids duplicates.
Why do my spaces turn into +?
That is the standard encoding for query parameters. Analytics tools decode them back to spaces, but hyphens give more readable reports.
Are my URLs sent to a server?
No. The URL is built in your browser.
