Frequently asked questions
Does allowing a crawler guarantee AI visibility?
No. robots.txt only controls access. It does not guarantee indexing, model training, ranking, mentions, or citations.
What happens if there is no robots.txt file?
In general, the absence of robots.txt means there are no robots.txt restrictions for the checked root URL.
