Does glassdoor.com block AI crawlers?
Yes, 3 of 17. As of October 19, 2026, glassdoor.com's robots.txt blocks CCBot, Bytespider and Diffbot from the whole site. It keeps the other 14 out of parts of the site. 10 of them are named in a group of their own; the others follow its rules for every crawler.
Its /llms.txt answered HTTP 403. The homepage answered HTTP 403 to ContextFetchBot, so there was nothing to measure.
Each crawler, by its robots.txt rules
From https://www.glassdoor.com/robots.txt (6,250 bytes, 15 user-agent groups), parsed per RFC 9309. Blocked: no path allowed. Partly blocked: some paths disallowed. The rule counts are those of the groups that apply.
