AI crawlers checked in robots.txt: GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-User, PerplexityBot, Google-Extended, CCBot, Applebot-Extended, Bingbot. The firewall check fetches your home page as GPTBot and as a browser and compares the answers. Measuring these signals does not guarantee any AI will cite a site — they make it possible.
