Add to Chrome, it's freeFree. No account. Nothing ever leaves your browser.
utm_source=facebook one day, Facebook the next, FB the day after. GA4 treats them as three different sources, splits your traffic three ways and never warns you. The report just looks a bit wrong.
The same source, the same medium, the same campaign naming, typed out again for every new link. It is dull, it is slow, and it is exactly the kind of task where a small slip goes unnoticed.
Three people, three habits, three spellings of the same campaign. By the end of the month the data is a puzzle, and someone has to spend an afternoon working out which rows belong together.
Fill in source, medium, campaign and the rest in labelled fields and the tagged URL builds itself as you type. No manual question marks, no forgotten ampersands, no guessing which parameter goes where.
Set up a template once, with the source and naming a client uses, and pick it next time from a list. Every link for that client starts from the same place, so the tagging stays identical across the whole account.
When the link is right, copy it with a single click and paste it straight into your ad platform, email tool or scheduler. No selecting text out of a spreadsheet cell and hoping you got the whole string.
Because the fields and templates decide the spelling, the same campaign is tagged the same way whoever builds the link. Your GA4 reports group properly, and nobody spends a morning reconciling three versions of one source.
UTM Builder Pro runs entirely in your browser. It builds the links on your device and stores your templates locally, and that is the whole of it.
No account, no sign-up, nothing sent to a server. Your client names and campaign details stay with you, not with us.
The full details are in the privacy policy, which is short, because there is not much to disclose.
You are launching a newsletter, three ad sets and a social push for one campaign: build every link from one template so all of it rolls up under a single, correctly spelled campaign name in GA4.
You manage links for eight clients with eight different naming conventions: keep a template per client and never again tag one client's link with another client's source by accident.
You just want the numbers to make sense: fill the form, copy the link, and know the tag matches what you used last week without checking.
Yes. Building UTM links, saving templates and copying tagged URLs are all free, with no account and no sign-up. There is no paid tier and no feature is held back.
Your templates live in your browser, on your machine. Nothing is uploaded to a server, ours or anyone else's. If you sign in to Chrome sync they may sync across your own devices, but they never reach us.
A UTM is a set of query parameters you add to a link so your analytics can tell where a click came from. If the same campaign is tagged three different ways, your reports split into three, and none of them tells the truth. Consistent UTM tagging keeps the numbers whole.
Yes. The links it builds use the standard utm_source, utm_medium, utm_campaign, utm_term and utm_content parameters that Google Analytics 4 reads. Tag your links consistently and your GA4 acquisition reports stay clean.
Yes, that is what the templates are for. Save a template per client or per campaign, with their naming already set, then generate every link for that client from the same starting point. No more copying last month's spreadsheet row.
Thirty seconds to install. A lot faster than unpicking a month of mismatched tags.
NUVIX builds focused, free tools for marketers and makers: small, sharp and doing one job properly. UTM Builder Pro handles the links; its siblings handle the rest of the workflow.
