How UTM parameters work

UTM parameters are query-string tags appended to URLs so Google Analytics can track where your traffic comes from. utm_source identifies who sent the traffic (e.g. a search engine or newsletter), utm_medium describes the marketing channel (cpc, email, social), and utm_campaign names the specific campaign. The optional utm_term and utm_content fields help differentiate paid keywords and ad variations.

To encode a UTM URL for safe use in HTML attributes, use URL Encoder. For other link tools, try URL Parser.

What this tool is used for

Building a tagged link for a campaign with consistent naming.
Producing one link per channel so the report separates them.
Adding term and content parameters for a paid or a test variant.
Checking a link's parameters before it goes into a send.
Producing links for a partner to use so attribution stays consistent.

Frequently Asked Questions

What order do the parameters go in?: Any order — they are query parameters, so nothing depends on position. Keeping a consistent order across a campaign is still worth doing, because it makes the URLs comparable at a glance and makes a missing parameter obvious in a list of hundreds.
Should I use hyphens or underscores in values?: Hyphens. Underscores are harder to see in an underlined link, and lower-case with hyphens is the convention most analytics teams settle on. What matters most is picking one and never deviating, since the values are case- and character-sensitive strings that will not be merged for you.
What happens if the URL already has a query string?: The parameters are appended with `&` rather than a second `?`, which is the difference between a working link and one that 404s. A URL with an existing fragment needs more care — the tracking parameters must go before the `#`, or they become part of the fragment and never reach the server.
Do UTM parameters work on any analytics platform?: They are a Google Analytics convention that most platforms now recognise, including Matomo, Plausible and Adobe. The five names are effectively universal; anything beyond them, like `utm_id` or platform-specific extras, is not, and will be dropped silently rather than reported.
Should the link be shortened afterwards?: It can be — shorteners preserve the query string through the redirect, so the parameters still arrive. What you lose is the ability to see the tagging in the link itself, which means a mistake is invisible until it shows up as unattributed traffic days later.

Common errors and gotchas

Mixing case between links, which splits one source into several in every report.
Tagging internal navigation, which restarts the session and destroys the original attribution.
Including an email address or an identifier in a parameter, which puts personal data in analytics.
Leaving the parameters on the page's canonical URL, which can fragment indexing.
Inventing a new naming convention per campaign, which makes historical comparison impossible.
