UTM builder.
Tag a link with where you will share it, so every visit lands in the right channel and campaign.
Questions.
What are UTM parameters?
Tags added to a link, such as ?utm_source=newsletter&utm_medium=email. Analytics tools read them from the landing URL to know where the visit came from, even when the browser sends no referrer.
Which ones do I need?
Source and medium are enough for most links. Add a campaign to group links from one launch or promotion. Term and content are for ad keywords and telling two links in the same email apart.
Should values be lowercase?
Yes. Many tools treat Newsletter and newsletter as two sources. Lowercase values and hyphens instead of spaces keep reports clean.
Where do UTM links matter most?
Places that hide the referrer: email, Discord, Slack, PDFs, QR codes and some apps. Without tags those visits look like direct traffic.
