UTM Link Builder

Add UTM parameters to a URL for campaign tracking in Google Analytics.

What this tool does

Builds a tagged link with utm_source, utm_medium, utm_campaign and optional term and content parameters, preserving any existing query string.

Who should use it

Marketers tracking email, social and ad campaigns.

How it works

The URL is parsed, UTM keys are set through URLSearchParams (so values are correctly percent-encoded) and values are lower-cased if requested to avoid duplicate report rows.

How to use it

  1. Enter or paste destination url in the form.
  2. Adjust the options below the main box if you need to; the defaults suit most cases. Use "Load example" to see how input should look.
  3. Press the run button. Processing happens instantly in your browser.
  4. Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.

Practical example

newsletter / email / spring_sale appended to https://example.com/landing.

Understanding the results

Warnings cover spaces and existing UTM tags. Do not use UTM links for internal navigation.

Limitations

UTM parameters can create duplicate URLs; make sure the landing page has a canonical tag.

Accuracy and report transparency

Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.

Privacy

Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.

Frequently asked questions

Why lowercase?

Google Analytics treats "Email" and "email" as different values.

Is my data sent to your server?

No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.

How accurate are the results?

Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.

Is this tool really free?

Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
