AI crawler access
for dictionary.com
dictionary.com allows every crawler that can cite it in an AI answer, while declining 3 training crawlers (GPTBot, Applebot-Extended, CCBot). That is the "cite but do not train" position.
That is below the 100% median across the 381 sites in this dataset. Resolved from https://dictionary.com/robots.txt on 13 August 2026.
Every crawler, and the rule that decided it
A crawler named directly in its own group is governed by that group. One not named falls back to the wildcard group. Where neither exists the crawler is reported as not listed — no policy has been expressed, and in practice most crawlers will proceed.

What this does and does not tell you
It tells you what dictionary.com states in its robots.txt, which is the file every well-behaved AI crawler consults before fetching. It is a stated preference and a voluntary protocol — not an access control, and not evidence about what any crawler actually did.
It also says nothing about whether the content is useful to an answer engine once fetched. Access is the precondition; extractable passages, visible dates, named authorship and sourced claims decide whether a reachable page is actually cited. That second layer is what the free evidence-readiness report measures.
Finally, robots.txt changes. This page reflects dictionary.com as it was on 13 August 2026. To see the position right now, run it through the live crawler access checker.
