Frequently asked questions
- Is Robots.txt Tester free to use?
- Yes. Robots.txt Tester is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.
- Where must robots.txt live?
- At the root of the domain, exactly at /robots.txt. A file placed in a subdirectory is ignored.
- Does robots.txt block a URL from appearing in search?
- No. It blocks crawling, not indexing. A blocked URL can still be listed without a description, so use a noindex tag when you want it removed.
- Why do duplicate User-agent groups matter?
- If a file declares the same user-agent twice, strict crawlers honour only the first group and silently ignore the second.
- Can robots.txt hide a page from AI crawlers?
- It can, and they generally honour it. If you want to be cited by answer engines, blocking them here removes you from the conversation entirely.
