Audit Guide
45% of your traffic has no meaningful channel attribution. "Direct" and "Unassigned" sessions add up to 41,600 sessions over this period. This means you can't tell whether your paid campaigns, email marketing, or social efforts are actually working. Roughly $34K in revenue happened in sessions that GA4 can't connect to any marketing channel. The root cause is that GA4's built-in channel rules don't match your actual traffic sources. For example, your Meta Ads traffic is arriving with a custom source/medium that doesn't match any default rule, so it falls through to "Unassigned."
