Frequently asked questions

Does robots.txt stop a page being indexed?

No. It stops crawling, not indexing. A disallowed URL can still be listed in search results — without a snippet — if other pages link to it. To keep a page out of the index, allow crawling and use a noindex meta tag.

Should I block AI crawlers?

It is a trade-off. Blocking prevents your content being used for training, but it also removes you from AI-generated answers that cite sources — an increasingly significant referral channel.
