How the UTM Builder works
The UTM Builder turns one destination page and one campaign name into a tagged link for every channel you plan to use. Instead of building a link for the newsletter, then another for Facebook, then another for a poster, you enter the details once, tick the channels and get the whole set together.
For each channel it sets utm_source to the platform and picks a utm_medium that GA4 recognises, such as social for Instagram or email for a newsletter. Next to every link it shows the GA4 channel the visit is likely to land in, so you can spot a medium that would end up as Unassigned before the link goes out. You can edit any medium by hand, and the Copy, CSV export, Check and QR buttons all use your edited version.
When to use it
Use it whenever you share a link to your own website from somewhere else: an email, a social post, a QR code, a partner's site or a message. You do not need it for links between pages on your own site, and with Google Ads auto-tagging switched on you usually do not need it for Google Ads either.
A worked example
A charity is promoting https://example.org/winter-appeal with the campaign name 2026-11-winter-appeal. They tick Newsletter, Facebook and Instagram. The builder returns three links, including:
https://example.org/winter-appeal?utm_source=newsletter&utm_medium=email&utm_campaign=2026-11-winter-appeal
In GA4 every visit from those links shares one campaign value, so the appeal's total appears in a single row, while source and medium show which channel did the work. They export the CSV and paste it into their campaign log before sending anything.
