UTM Link Builder
Add UTM tracking parameters to a link so you can see in analytics exactly where your traffic came from.
Tagging a link so you know what worked
UTM parameters are the little tags on the end of a URL — source, medium, campaign and more — that tell your analytics where a visitor came from. Without them, traffic from your newsletter, a social post and a paid ad can blur together; with them, each is labelled so you can see which channel and which campaign actually drove visits. This builds correctly tagged links from your inputs.
Fill in the campaign details and it assembles the tagged URL, ready to share.
Consistency is everything
The one rule that makes UTMs useful is naming discipline. Analytics treats Facebook, facebook and FB as three different sources, so a single inconsistent capital letter splits your data and muddies the picture. Agree a convention — lowercase, consistent names for each channel and campaign — and stick to it every time. Also keep UTMs on external links only, never on internal links between your own pages, where they overwrite the real referrer.
Frequently asked questions
What do UTM parameters do?
They label a link with its source, medium and campaign so your analytics can attribute the visit to the right channel.
Why do my sources look duplicated in analytics?
Inconsistent capitalisation — Facebook and facebook count separately. Keep naming lowercase and consistent every time.
Is anything uploaded?
No. The link is built in your browser.
