Why is not ChatGPT citing my B2B SaaS?

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

What is llms.txt and do I need it?

llms.txt is a proposed markdown file at /llms.txt that summarizes a site for language models and links its key pages. You do not need it for AI search visibility: Google says Google Search ignores it, and no major AI engine documents using it to choose citations. Some coding agents do fetch it.

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

Schema.org. JSON-LD identifies your entities (Organization, Product, Person) per page and powers Google rich results. llms.txt is a proposed site summary that Google Search ignores and that no major AI engine documents using to choose citations. Treat it as optional.

Why is my AI Readiness score low?

Low AI Readiness tool scores reflect missing evidence across five categories: bot discoverability (30 points), structured data (25), LLM communication (25), content accessibility (15), and cross-signal readiness (5). Review the category breakdown for lost points. This tool score differs from the overall Radar dashboard average.
