What this means
vocabulary.com follows a pattern many publishers now use: it keeps AI training crawlers like GPTBot, CCBot, Applebot-Extended out, but still lets AI search and live-browsing agents in. That way it can still be cited and linked in ChatGPT or Perplexity answers.
Among the 92 reference & knowledge sites in our AI crawler report, 27% block GPTBot completely. vocabulary.com is one of them.
