A referral count means more when you can compare it to something. The Referrals tab in AI Traffic shows your share of visitors from AI: visits from AI answers as a share of every visit your analytics counted over the same 7, 30 or 90 days. When both periods are fully measured, you also see how it changed from the period before.
The share comes from GA4 or PostHog, so connect one of them to see it. If a few sessions can't be traced to a source, you still get the number, with a note saying how many. Your own tools can read the same figure over API v2 and MCP.
