What are UTM parameters?
UTM parameters are short tags added to the end of a link, like ?utm_source=instagram&utm_medium=social&utm_campaign=spring_sale. Analytics tools such as Google Analytics 4 read them and group visits by where they came from, so you can compare your Instagram bio with your newsletter or a paid ad.
Use utm_source for the site or app (instagram, newsletter), utm_medium for the type of traffic (social, email, paid_social) and utm_campaign for what you're promoting. utm_content is useful for telling apart two links in the same place, such as bio versus story. Keep values lowercase and consistent, because GA4 treats Instagram and instagram as different sources.
Long tagged links look messy in a bio. Put them behind a link in bio page or a short link instead, and keep the tags for your own reporting.
Put it all behind one link.
Link in Bio turns the link in your bio into a page with all your links, forms, analytics and QR codes. Want more free tools? See them all.

Is this UTM builder free?
Yes. It's free with no sign-up and runs entirely in your browser, so your URLs are never sent anywhere.
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign. utm_id, utm_term and utm_content are optional.
Do UTM links work with Google Analytics 4?
Yes. GA4 reads all standard UTM parameters, including utm_id, and shows them under Traffic acquisition as session source, medium and campaign.
Will UTM parameters break my link?
No. Existing query parameters and #anchors on your URL are kept; the UTM tags are simply added alongside them.
