Why is not ChatGPT citing my B2B SaaS?

ChatGPT cites sites it treats as authoritative for a query. Most B2B SaaS sites lack three specific signals: structured data declaring entity identity, an llms.txt file, and citations from domains ChatGPT already trusts.

What is llms.txt and do I need it?

llms.txt is an emerging markdown spec that tells AI engines what your site is about, what content they should prioritize, and how to use it. It sits at /llms.txt. If your buyers research vendors via ChatGPT, Claude, Perplexity, or Gemini, yes — you need it.

Schema.org vs llms.txt: which AI search signal matters most?

Both matter and they do different jobs. Schema.org JSON-LD identifies your entities (Organization, Product, Person) per-page for machine parsing. llms.txt is a site-level declaration of what your site is about, what content to prioritize, and how AI engines should use it. Ship both.
