## Tools (1)

- `check_site`: Checks one public website's readiness for AI search, free and without an account: whether AI crawlers are allowed in, whether the pages can be read without running JavaScript, the structured data, titles and descriptions, llms.txt and more - the same fetch-only check as therankingfactory.com/audit. Answers with each finding's title and tier (Blocker first), every check made with its result, and fullReport: the link where the person can have the full report, with what to do about each finding, emailed to them. It does not ask any AI engine whether the business is named or cited; that needs an account. One site per call, and a site can be checked a limited number of times a day.
