Free UTM link builder
Add source, medium and campaign tags to a URL so your analytics can tell which channel a visit came from. The tool lowercases values, flags spaces and keeps your naming consistent.
Free. No sign-up. Runs in your browser: what you type is not sent to us.
The three tags that matter
Source says where the visit came from (a newsletter, a platform, a partner). Medium says the type of channel (email, social, referral, cpc). Campaign names the specific push. Term and content are optional extras for paid keywords and for telling two links in one email apart.
Pick a naming rule and stick to it
Analytics treats Email and email as different values. Decide on lowercase, no spaces and a consistent pattern such as month-product-channel, write it down, and use it for every link.
Do not tag internal links
UTM tags are for links from outside your site to your site. Putting them on links between your own pages can break the original source of a visit.
Shorten before sharing
Long tagged URLs look untidy in social posts and print. Use your own short link or a link-shortener you trust, and test that the tags survive the redirect.
Questions people ask
Do UTM tags change what visitors see?
No. They are only read by analytics tools. The page loads exactly as before.
Do I need Google Analytics for this?
No. Any analytics tool that reads UTM parameters, including simple server-side counters, can use them.
Is my URL sent to you?
No. The link is built in your browser.
