UTM link builder
Creates trackable links so you know where your visits come from.
Your browser does the calculations: what you type is never sent or stored.
What UTM links are
They are tags you add at the end of a link, after the question mark. They don't change the page: they tell analytics tools (like Google Analytics) where the visit comes from. Without them, visits from your newsletter get mixed up with all the others.
The three tags you always need
utm_source is who sends the visit (newsletter, instagram). utm_medium is the type of channel (email, social, cpc). utm_campaign is the campaign name (evening-tea-launch). Always write them the same way, in lower case and with hyphens: the tool does it for you.
An example
For the October newsletter of Five Leaf, the Peacchy practice company: fiveleaf.example/evening-teas?utm_source=newsletter&utm_medium=email&utm_campaign=evening-teas-october.
Note: UTM tags don't collect any data on their own. Visits are measured by the website's analytics tool, which must respect cookie consent.
