Pick a preset or fill in the tags to build a tracked link. The builder shows which GA4 channel the link lands in and flags tags GA4 can't group, like source=x on paid ads.
The page people land on

utm_medium, required
utm_campaign, required. Add a date to keep campaigns apart, like 2026-10_launch.

FAQ
UTM Campaign URL Builder questions.
What are UTM parameters?
Tags added to a URL that tell analytics where a visit came from. The five are source, medium, campaign, term and content. Source, medium and campaign are the core three you should always set.
Why keep UTM tags consistent?
Analytics treats Facebook and facebook as different sources, fragmenting your reports. Pick a lowercase convention and stick to it. The builder keeps formatting clean so your data stays tidy.
Do UTM links affect SEO?
Use them for outbound campaign links in ads, email and social, not for internal links. On internal links they can split analytics and create duplicate URLs. Set a canonical tag to be safe.
Which GA4 channel will my link show up in?
GA4 groups traffic with fixed rules: medium cpc from a search engine is Paid Search, medium email is Email, medium referral is Referral. The builder applies the same rules and Google's published list of search, social, video and shopping sources.
Will the parameters be visible to users?
Yes, they appear in the URL. That is fine for campaign links. If you want a tidy link to share publicly, shorten the tagged URL with a link shortener afterwards.
