The User-agent: * fallback

Important: Robots rules are requests to compliant bots. They do not prove identity, enforce privacy, block a person, remove a page from search, or guarantee crawling, indexing, training exclusion, or citation.

What the builder covers

It writes rules for each bot listed above and one fallback for unlisted bots. It does not claim to list every crawler. Provider names and controls can change.

Check the direct provider sources

Custom and verified agents

This starter does not add a custom user-agent field. A custom name may be wrong or may hide how a vendor really fetches pages. Check the provider record, add any needed group to the downloaded file, and test the final policy on the live site.

What it cannot do

It cannot prove a bot is real, change a firewall, protect private data, or promise search or AI results. Keep private data behind access control and test the final file through the live edge.
