What are UTM parameters?

UTM parameters are short tags added to the end of a URL so analytics tools such as Google Analytics can show which campaign, channel, and ad brought a visitor to your site. They do not change the page people see.

The five UTM parameters

utm_source Required
Where the traffic comes from, such as google, newsletter, or facebook.
utm_medium Required
The type of channel, such as cpc, email, or social.
utm_campaign Required
The specific campaign, promotion, or launch, such as fall-sale-2026.
utm_term Optional
A paid search keyword or audience name.
utm_content Optional
Tells similar links or ads apart, such as header-link versus footer-link.

UTM naming tips

  • Use lowercase. Analytics tools treat "Email" and "email" as different values.
  • Use hyphens or underscores instead of spaces, and pick one style and stick with it.
  • Use common mediums like cpc, email, and social so Google Analytics 4 sorts your traffic into the right channels.
  • Keep names short, descriptive, and consistent across your whole team.
  • Do not add UTM tags to links inside your own website. They can overwrite the visitor’s original traffic source in your reports.
  • Never put personal information such as names or email addresses in UTM values. URLs are visible and often logged.

UTM Builder FAQ

Is the Gaemster UTM Builder free?

Yes. It is free to use, with no account or sign-up.

Does the UTM Builder store my URLs or campaigns?

The builder runs in your browser and does not send your URLs or campaign history to Gaemster. Saved campaigns are kept in your browser storage on this device, and clearing your site data removes them.

Which UTM parameters are required?

This builder requires campaign source, medium, and name, which is enough for most reports. Campaign term and content are optional.

Do UTM links work with Google Analytics 4?

Yes. The links use the standard utm_ parameters that Google Analytics 4 and most other analytics tools read.

Why should UTM values be lowercase?

Analytics tools treat "Email" and "email" as two different values, which splits your data. Using lowercase everywhere keeps your reports clean.

What happens if my link already has a query string?

The builder keeps your existing parameters and adds the UTM tags. If the link already has UTM tags, they are replaced and you will see a note.

Does the UTM Builder work on my phone?

Yes. It works on phones and tablets. Saved campaigns are stored per device and browser, so use Export CSV to move them elsewhere.
