UTM Builder (Campaign URL Generator)
Build a campaign URL with correctly encoded UTM parameters (source, medium, campaign, term, content), to measure traffic sources in Google Analytics and similar tools.
What each UTM parameter is for
The 5 standard parameters, with a real usage example:
| Parameter | What it's for | Example |
|---|---|---|
| utm_source | Where the traffic comes from | newsletter, google, facebook |
| utm_medium | Channel type | email, cpc, social |
| utm_campaign | The specific campaign's name | summer-launch-2026 |
| utm_term | Paid keyword (if applicable) | mortgage calculator |
| utm_content | To tell apart variants of the same link | top-button, bottom-button |
Why to always use the same values
Google Analytics and similar tools treat "Email" and "email" as two different sources — for reports to group traffic correctly, always use the same values (usually lowercase, no spaces) for the same source or channel across all your campaigns.
