UTM Campaign URL Builder

Base URL & Validation

The tool auto-cleans your base URL before appending tracking params:

• Protocol — missing http:// / https:// is added automatically. Only http/https/mailto are allowed.
• Query merge — if the URL already has a query (e.g. ?id=5), the UTM parameters are appended with a & so existing params are preserved.
• Fragments — any #hash is kept intact at the very end of the URL.

utm_source

Where the traffic is coming from — the referrer of your traffic. Typical values: newsletter, google, facebook, twitter, linkedin.

This parameter is required; the tool will not build a final URL without it.

utm_medium

How the campaign is delivered. This is a required parameter. Standard values:

• email — email marketing
• cpc — cost-per-click paid search
• social — social media posts
• cpm — paid display
• affiliate — partner links
• organic — free search

The tool offers common choices but you may type any value.

utm_campaign

The name of the campaign that ties this URL to a marketing effort. This is a required parameter.

Convention is to keep it readable and lowercase-hyphenated, e.g. spring-sale-2026, but any value is accepted and will be URL-encoded.

Encoding & Query Merge

Every parameter value is passed through encodeURIComponent so spaces, &, =, and non-ASCII characters become safely encoded. The breakdown table shows both the encoded form sent in the URL and the decoded value you entered.

Optional parameters (utm_term, utm_content) are included only when you provide a value — empty fields produce no parameter.

Output & Copy

Ready means: a valid base URL plus the three required params (source, medium, campaign) are present. The final URL is assembled and the copy button transfers it to your clipboard.

The breakdown table underneath lists each UTM parameter, its encoded value as it appears in the URL, and its decoded value for verification.
