UTM link builder

UTM link builder: what it is for

Paste the page address and fill in source, medium and campaign, or use the ready-made shortcuts (Instagram bio, stories, WhatsApp, email, Google Ads, Meta Ads and printed QR code). utm_term and utm_content are optional.

The tool standardizes the values (lowercase, no accents and hyphens instead of spaces), replaces UTMs already in the link and keeps the last 15 copied links in this browser.

How to use

1. Paste the page address.
2. Pick a shortcut or fill in source, medium and campaign.
3. Copy the link and use it in your bio, ad or message.

When to use it

• Knowing how many visits come from your bio link.
• Comparing campaigns on WhatsApp and email.
• Measuring QR codes on flyers and menus.

Frequently asked questions

What are UTM parameters for?

They tag the link with the source of the visit. In Google Analytics 4 you can see, under Acquisition, how many visits and sales came from each source, medium and campaign, for example from your Instagram bio link or an email newsletter.

Which fields are required?

Always use utm_source (where: instagram, whatsapp, newsletter), utm_medium (the type: social, email, cpc) and utm_campaign (the name of the action: black-friday). utm_term and utm_content are optional, for a keyword and to tell ads or buttons apart.

Does capitalization matter?

Yes. For Analytics, Instagram and instagram are different sources. The tool lowercases everything and replaces spaces with hyphens to keep reports tidy.

Can I use UTM on internal links?

It's not recommended: a UTM on an internal link starts a new session in Analytics and wipes out the real source of the visit. Only use it on links pointing to the site from outside.
