theatlantic.comIts robots.txt (the public rules file for bots) treats AI bots differently from each other. It blocks 13 of the 24 AI bots we track from the whole site, including ClaudeBot, Google-Extended, Applebot-Extended, CCBot and Meta-ExternalAgent. GPTBot, OAI-SearchBot and ChatGPT-User can reach most of it. The homepage also turned our bot, which says who it is, away (HTTP 403).

Bots for AI search Some blocked

AI assistants Some blocked
5 of these 7 companies say their assistants may ignore robots.txt.

We test two pages: the homepage, and a made-up page that stands in for the rest of the site. "Blocked" means both are off limits. "Some pages blocked" means only one is. Rules for search results, carts, checkout and accounts don't change these labels, because almost every site keeps all bots out of those pages.
