Sources and channels

A visit’s source is the referrer of its first page. Your own domains count as direct.

Channel	Examples
ai	chatgpt.com, perplexity.ai, claude.ai, gemini.google.com, copilot.microsoft.com
search	Google (any country domain), Bing, DuckDuckGo, Brave Search, Ecosia
social	X, LinkedIn, Reddit, YouTube, Hacker News, Bluesky, Mastodon
referral	any other site
direct	no referrer, or your own site

Hosts are matched as whole labels: notgoogle.com and google.evil.com are referrals.

UTM parameters (utm_source, utm_medium, utm_campaign) of the first page are kept with the visit.

API: GET /v1/sites/{id}/stats/sources?by=channel (or referrer, utm_source, utm_medium, utm_campaign, entry_page).
