GA4 channel checker
Preview the channel group before you launch
Default channel grouping in GA4 is a ruleset, not a guess. Type the source and medium you plan to use. This is a hint based on common rules — confirm with a test click in your property.
Safe mediums for default groups
cpc or ppc lean Paid Search. paid_social leans Paid Social. social leans Organic Social. email is Email. display is Display. affiliate is Affiliates. Mediums like ad, banner, and promo often sit in Unassigned. Longer explanation: fix Unassigned traffic and how GA4 reads UTMs.
If the hint says Unassigned, change the medium in the builder or run a full URL through the validator.
