— What it does

The UTM Link Builder is a free tool that appends Urchin Tracking Module (UTM) parameters to a link so analytics tools can attribute traffic to the right source, medium, and campaign. Enter your base URL and the campaign values — it URL-encodes each parameter, joins them with the correct ? or & separator, and keeps any existing query string and hash intact. Everything runs in your browser, so your URLs are never uploaded.

  • Covers all five UTM parameters: source, medium, campaign, term and content.
  • URL-encodes every value and preserves existing query parameters and the #hash.
  • Validates the base URL and only emits the parameters you actually fill in.
  • Runs entirely in your browser — nothing you build is uploaded to a server.

How to use it

1

Paste your base URL

Enter the page you want to link to. Existing query parameters and any #hash are kept.

2

Fill in the campaign values

Add utm_source, utm_medium and utm_campaign (the core three), plus optional utm_term and utm_content.

3

Copy your tagged URL

The full tracking URL updates as you type — copy it and use it in your ad, email, or post.

Frequently asked

What are UTM parameters?
UTM parameters are tags added to a URL (utm_source, utm_medium, utm_campaign, utm_term, utm_content) that analytics tools like Google Analytics read to attribute a visit to a specific marketing campaign and channel.
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign are the core three most analytics setups expect. utm_term and utm_content are optional and usually used for paid keywords and A/B variants.
Will it break a URL that already has parameters?
No. The builder detects an existing query string and appends with & instead of ?, and it preserves any #hash fragment, so your original URL keeps working.
Are my URLs sent anywhere?
No. The link is assembled locally in your browser with JavaScript. Nothing you enter is uploaded to a server, so internal or unpublished URLs stay private.
