Frequently asked

Which parameters are required?

GA4 treats `utm_source`, `utm_medium`, and `utm_campaign` as required — without all three, a hit won't be attributed to the campaign. `utm_id`, `utm_term`, and `utm_content` are optional supplements.

Should I use lowercase?

Yes. UTM values are case-sensitive in every major analytics tool — `Newsletter` and `newsletter` will show as different campaigns and split your data. Pick a naming convention (lowercase + underscores is common) and enforce it.

Will existing query params be preserved?

Yes. If your URL already has `?ref=x`, the tool keeps it and adds UTM params alongside. If you're re-editing a link, existing utm_* values are updated in place.
