Short answer: llms.txt is a short file at the root of your website that summarizes who you are and links to your key pages for AI tools. Schema markup labels your business details in a machine-readable format. Allowing AI crawlers ensures these tools can read your site at all.
AI crawlers
Check your robots.txt and firewall settings for bots such as GPTBot, OAI-SearchBot, PerplexityBot, Google-Extended and Bingbot. Blocking them may keep your site out of AI answers.
Schema markup
Useful types: Organization, LocalBusiness or a professional type (LegalService, Dentist, MedicalClinic, AccountingService), Service, FAQPage, Person for key professionals. Mark up only information that is visible on the page and true.
llms.txt
A simple Markdown file following the llmstxt.org format: your name, a one-paragraph summary and links to your most important pages. It is low-effort and low-risk, though AI tools differ in how much they use it.
Priority order
Crawler access first, then accurate schema, then llms.txt.
