Build one clean UTM link.

A UTM link is an ordinary web address with campaign tags added to its query string: utm_source, utm_medium, utm_campaign, and optionally utm_content and utm_term. The page that opens is the same page. The tags tell your analytics tool where the click came from, so a newsletter click and a Reddit click show up as two sources instead of one blur.

Source names the site or sender the click came from: newsletter, reddit, producthunt. Medium names the kind of channel: email, social, cpc, referral. Campaign names the push itself: launch-week, spring-sale. Google Analytics reads source and medium to attribute the session and campaign to group the traffic, which is why IndieUTM asks for all three before it builds a link.

Content tells two links in the same campaign apart, such as header-button and footer-link. Term holds the paid keyword.

Yes. Google Analytics treats Newsletter and newsletter as two different sources, and the same goes for every tag. Pick lowercase, with hyphens between words, and keep it that way across every link. A preset in IndieUTM saves one spelling of source, medium, and campaign, so the next link in the same channel starts from the same values instead of fresh typing.

Yes. Paste the tagged link into the destination field. IndieUTM moves its UTM tags into the tag fields and leaves the rest of the address alone: every other query parameter and the #fragment stay exactly as written, with their original encoding. Change what you need and build again. A tag you changed is rewritten in its original place, a tag you emptied is removed, and a new one is added at the end.

No. Presets and the eight most recent links live in this browser's local storage, on this device, and nowhere else. IndieUTM keeps up to twenty presets. Clearing site data, using a private window, or switching browsers starts from an empty list. If you need the same presets on a second machine, save them there once more.

Not on their own. The tags do not change the page, and Google does not rank a page by its campaign tags. The one risk is duplicate addresses: if a tagged link gets crawled and indexed, search can show /pricing?utm_source=newsletter beside /pricing. A rel=canonical tag pointing at the clean address settles that. Use UTM tags on links you share elsewhere, not on links inside your own site.

Yes. No account, no card, no premium plan, no upgrade nag, no hidden paywall. IndieUTM is free, all of it.

There is no public lookup history. A network check sends the public input needed for that check to its named source. Local file tools process file contents in your browser. Analytics is currently off, so no visit or job data is sent to a tracker. Anything the tool saves for you stays in your browser.
