How it works

Enter your base URL and the campaign parameters — source, medium, campaign name, and optional term and content — and the tool appends them as properly URL-encoded utm_ query parameters. The result is a trackable link that analytics tools read to attribute traffic to the right campaign. It handles existing query strings and encoding for you. Everything runs locally in your browser; no link or data is sent anywhere.


              ?utm_source=…&utm_medium=…&utm_campaign=…

Common use cases

  • Tagging a newsletter link so clicks show up under the right campaign.
  • Building consistent UTM links for a paid ad set.
  • Tracking which social post drove traffic.

Frequently asked questions

Which UTM parameters are required?

Source, medium, and campaign are the core three most analytics setups expect. Term and content are optional, typically used for paid-search keywords and A/B distinguishing.

Does it encode special characters?

Yes. Each parameter value is URL-encoded, so spaces and symbols in your campaign names produce a valid, working link.

What if my URL already has a query string?

The builder detects an existing query string and appends the UTM parameters with & instead of ?, keeping the link valid.
