Frequently asked questions
Which UTM parameters are required?
Google Analytics requires utm_source, utm_medium and utm_campaign at minimum. The others (term, content, id) are optional.
Should I use lowercase?
Yes. GA treats "Email" and "email" as different sources. Forcing lowercase prevents fragmented data.
Where do UTM parameters show in GA4?
Under Acquisition → Traffic acquisition. Source, medium and campaign appear as dimensions for session grouping.
