UTM builder questions
Which UTM tags are required?
GA4 needs utm_source to attribute the visit, and you should add utm_medium and utm_campaign too. utm_term, utm_content and utm_id are optional.
Are UTM values case-sensitive?
Yes. "Facebook" and "facebook" show as two sources, which is why the tool lowercases values by default.
Should I use UTM tags on internal links?
No. Tagging links between your own pages starts a new session with the wrong source. Use them only on links from outside your site.
