A UTM link is five query parameters bolted onto a URL so your analytics can tell where a visitor came from. Typing them by hand is where launch reporting quietly goes wrong: one capital letter, one stray space, and Twitter and twitter become two rows in your dashboard that you then have to add together by eye.
- Source, medium and campaign are the three that matter. Term and content are optional and mostly useful for paid ads, where you are running several variants of the same campaign and need to tell them apart.
- Keep everything lowercase. Analytics platforms treat parameter values as case-sensitive strings, so Newsletter and newsletter split one campaign into two — the single most common way a launch report ends up wrong.
- Never put a UTM on an internal link. Tagging a link from one of your own pages to another restarts the session and credits the visit to whatever source you typed, which overwrites the real one that brought them in.
- Anything you type here stays in your browser. The link is assembled locally and never sent anywhere.
Questions
- What is the difference between utm_source and utm_medium?
- Source is where the click came from — a specific site or product, like linkrena or a newsletter name. Medium is the kind of channel it arrived through, like referral, email or social. Source answers "who sent them", medium answers "how".
- Do UTM parameters hurt SEO?
- Not on links other people click, which is what UTMs are for. They can cause duplicate-content confusion if a tagged URL gets indexed, so make sure the destination page has a self-referencing canonical tag — most sites, including ours, already do.
- Should I use UTMs on my launch link?
- Yes, if you are posting the same link in several places. It is the only way to know afterwards whether the traffic came from your post, someone else’s share, or the directory listing itself.
