UTM Parameters Explained Simply: What Are They For?

What does a link with UTM parameters look like?

A UTM parameter is added after a question mark at the end of the address, and several parameters are separated by the & sign. Example: https://example.com/offer?utm_source=newsletter&utm_medium=email&utm_campaign=fall-2026.

The page that opens is exactly the same as without UTM. Only the measurement tool reads these tags to classify the visit.

What goes in source, medium and campaign?

Three parameters are enough in most cases, and they are the ones Google presents as the main ones in its campaign URL builder.

• utm_source: the exact origin of the click. Examples: newsletter, instagram, linkedin, a partner’s name.
• utm_medium: the type of channel. Examples: email, social, cpc (paid ads), qr, poster.
• utm_campaign: the name of the campaign. Examples: fall-2026, black-friday, guide-launch.
• utm_term and utm_content, optional: the keyword bought in paid advertising, and the exact element that was clicked (the top or bottom button, for example).

Where do you read the results in Google Analytics?

In Google Analytics 4, open the acquisition reports: you can group visits by channel, source or medium, and by campaign. GA4 sorts visits into default channels (Email, Social, Paid Search…) based on the source and medium. Conventional values like email or cpc are recognized, while an invented medium may put the visit under “Unassigned.”

If you see “(not set)” or an unexpected channel, first check the spelling of your parameters. Data can also take a few hours to show up.

Which common mistakes should you avoid with UTM?

Most problems come from sloppy naming. Google Analytics tells uppercase from lowercase: “Newsletter” and “newsletter” show up on two separate lines.

• Pick simple rules and stick to them: all lowercase, hyphens instead of spaces, stable names.
• Do not use UTM on internal links within your own site: you would overwrite the real origin of the visit.
• Never put personal data in a UTM (email address, name): it would be passed to the analytics tool.
• Keep a table of your conventions and campaigns, so everyone names things the same way.

Why combine UTM and a short link?

An address with three or four parameters gets long and ugly. Behind a short link it is no longer a problem: the visitor sees a clean address, and the analytics tool receives the tags. You can also create one short link per channel, each with its own UTM, to the same page.

In Qlynk, the Pro plan offers a UTM builder on the link edit page, with source, medium and campaign, which adds the parameters to the destination address for you.

Do you still need an analytics tool?

UTM only matter if an analytics tool is installed on your landing page: without one, nobody reads the tags. On the other hand, a short link with stats counts clicks without installing anything, but cannot see what visitors do next on your site. The two complement each other. If you use Google Analytics, think about your visitors’ consent: see the guide on short links and GDPR.

How do you name campaigns so they last?

The real work of UTM is not writing them, but naming them consistently for months. Choose one rule, only one, and write it down in a shared table.

A simple convention: the source is the platform or partner name (newsletter, linkedin, partner-smith), the medium is the channel type (email, social, qr, poster), and the campaign is the name of the operation followed by the year (fall-2026). All lowercase, with hyphens, no accents or spaces.

This gives readable reports: at a glance, you see that the fall newsletter did better than the poster. Without a convention, within a year you will have eight spellings of the same source. If you work with others, or with an agency, share the convention before you create the first link, not after. Also plan a way to find your links: a table with the date, the channel, the target page and the full link is enough. In three months, you will be glad you do not have to reconstruct from memory what “promo-v2-final” meant.
