UTM parameters are five query-string tags; source, medium, campaign, content and term, that analytics tools read to attribute a visit. Source, medium and campaign are the three that matter; content and term are optional. Google Analytics treats them as case-sensitive, so Email and email become two separate rows.

How to build a UTM link

1 Paste the page the link should land on.

2 Fill in source, medium and campaign. The presets are the values Analytics recognises as standard channels.

3 Copy the finished link. Leave the lower-case switch on unless you have a reason not to.

Medium is the field that decides which channel group a visit lands in, and it is where most tagging goes wrong. Use email, cpc, social, referral, affiliate or display; anything else falls into "unassigned" and quietly disappears from the default reports. The other common mistake is inconsistent casing, which is why the lower-case switch is on by default.
