Does dictionary.com block AI crawlers?

Yes, 3 of 17. As of October 19, 2026, dictionary.com's robots.txt blocks GPTBot, Applebot-Extended and CCBot from the whole site. It keeps the other 14 out of parts of the site. 3 of them are named in a group of their own; the others follow its rules for every crawler.

It has no llms.txt (HTTP 404). Its homepage is 16,287 tokens of raw HTML, 69 as Markdown (0.4%) and 69 pruned for the question “What is dictionary.com?”.

Each crawler, by its robots.txt rules
