UTM Builder

Build UTM tracking links for your marketing campaigns. Enter your URL and campaign details to generate a tagged link ready to share.

You shared a link on social media, in an email and in an ad — and the visitors came. But which one actually worked? Without tracking, all three look the same in your analytics: just visitors. UTM parameters are small tags you add to a link that answer that question. They tell Google Analytics exactly where each click came from, so you can see which campaign, which channel and even which specific post brought people to your site — and spend your effort on what works.

What is UTM Builder?

UTM Builder is a free online tool that builds tracked campaign links with UTM parameters. Enter your website URL and your campaign details, and it generates a tagged link that is ready to share. When someone clicks that link, Google Analytics records the source, medium and campaign name, so you can measure exactly how that link performed.

The tool runs entirely in your browser. The links you build are processed on your own device and are never uploaded to a server or stored, so your campaign details stay private. It works on Windows, Mac, Chromebook, Android and iPhone — anything with a modern web browser.

The five UTM parameters

• utm_source — where the traffic comes from, for example google, facebook or newsletter.
• utm_medium — the type of channel, for example cpc, email or social.
• utm_campaign — the name of the campaign, for example summer-sale or product-launch.
• utm_term — the search keyword, mainly used for paid search ads.
• utm_content — which version of the link was clicked, useful when you test two versions of the same ad or email.

A finished link looks like this: https://example.com/?utm_source=newsletter&utm_medium=email&utm_campaign=summer-sale. The page itself does not change — the tags only tell your analytics where the visitor came from.

What you can use it for

• Email campaigns: see which newsletter actually brings visitors and sales.
• Social media: compare Facebook, Instagram and X to see which one sends the most traffic.
• Paid ads: track which ad and keyword earns its money back.
• Print and QR codes: tag a link on a poster or business card to see whether anyone scans it.
• Testing: use utm_content to compare two versions of the same link and keep the winner.

How it works

Using this free UTM builder is simple:

1. Enter your Website URL.
2. Fill in the required fields: utm_source, utm_medium and utm_campaign — and add utm_term or utm_content if you need them.
3. Copy your finished tracked link and share it wherever the campaign runs.

Frequently asked questions

Is UTM Builder free?

Yes, it is completely free to use, with no account or sign-up needed.

Do UTM parameters change the page?

No. The parameters are only labels for your analytics. The page loads exactly the same for the visitor — they just see a longer link in the address bar.

Which parameters are required?

Source, medium and campaign are the three that matter most — without them, your analytics cannot tell one link from another. Term and content are optional, for when you want more detail.

Should I use UTM tags on internal links?

No — use them only on links that bring people to your site from outside, such as emails, ads and social posts. Tagging links inside your own site would confuse your analytics and overwrite the real source of the visit.

Good to know

• Be consistent with names: use lowercase, short words and dashes, and use the same names every time so your reports stay tidy.
• Keep a simple list of the campaign names you have used, so two people do not tag the same campaign differently.
• To send people to your site from print, pair a tagged link with a QR code — the code carries the tracking, and the scan still counts.
