UTM Link Builder
UTM parameters tell your analytics tool where a visit came from. This UTM link builder adds source, medium and campaign to any web address so marketers, founders and agency teams can tag newsletter links, social posts and partner links consistently instead of hand-typing query strings.

What this marketing tool gives you
The result is the full tagged link, followed by a short list of the source, medium and campaign values you used. Copy it straight into the email or post, or keep it in the campaign brief for reference. The fields are held in your browser for the next link, with no account involved.
What you enter
- Base URL: the page address, starting with http:// or https://
- Source: where the traffic comes from, such as newsletter or linkedin
- Medium: the type of channel, such as email or cpc
- Campaign: the campaign name, such as spring-shops
Worked example
The example uses the base URL https://fieldnote.example/pricing with source newsletter, medium email and campaign spring-shops. The tool returns https://fieldnote.example/pricing?utm_source=newsletter&utm_medium=email&utm_campaign=spring-shops, which Google Analytics and similar tools will read as an email visit from the newsletter. Other query parameters on the base URL would be kept.
How does a UTM link work?
The tool reads your base URL and sets three query parameters: utm_source, utm_medium and utm_campaign, using the values you typed. Any other parameters already on the URL are kept. If the URL already has one of these three UTM parameters, its value is replaced by the new one.
All four fields are required. The base URL must start with http:// or https://; anything else produces a warning. Values are URL-encoded where needed, so spaces and special characters are made safe for the address bar.
Tips before you use the result
- Agree a short list of lowercase sources and mediums and reuse them; "Email" and "email" show up as different rows in most reports.
- Use hyphens instead of spaces in campaign names so links stay readable.
- Never put UTM tags on internal links within your own site; they overwrite the original source of the visit.
- Keep the tagged links in the campaign brief so anyone can match a report row back to the exact link.
Frequently asked questions
What are UTM parameters?
They are tags added to the end of a URL that analytics tools read to attribute a visit. utm_source names where the visitor came from, utm_medium names the type of channel, and utm_campaign names the specific campaign. This builder adds those three.
Does this tool add utm_term and utm_content?
No. It sets utm_source, utm_medium and utm_campaign only. If your base URL already contains utm_term or utm_content, those parameters are kept as they are, because the tool leaves other query parameters untouched. Add them by hand after copying the link if your reporting relies on them.
Why do I get a warning about my base URL?
The base URL has to be a full web address beginning with http:// or https://. A bare domain like example.com, or a link with another scheme, will not be accepted. Paste the full address from your browser's address bar. Then run it again.
Will a UTM link break my page?
Normally not. UTM parameters are ignored by most websites and read only by analytics scripts. Existing query parameters on your URL are preserved, so filters or tracking you already rely on keep working. Test the tagged link once before sending it widely.
