How GA4 Groups Traffic
Default channel groupings sort visits into categories like Organic Search, Paid Search, Direct, Social, and Referral based on the referring source.
The Truth About “Direct” Traffic
A large “Direct” bucket often hides broken tracking, app links, or dark social shares — not just people typing your domain from memory.
Using UTM Parameters
Add utm_source, utm_medium, and utm_campaign tags to links you share so campaign performance shows up precisely instead of blending into “Referral” or “Direct.”
