Tidio has a 251-line llms.txt. Crisp has zero. The score gap: +29 points. This single file tells AI assistants exactly what your site does -and without it, they're guessing.

Sitemaps tell crawlers what exists. RSS feeds tell them what changed. If you don't have one, your new content waits days -or weeks -to be discovered.

Voice assistants need to pick which paragraph to read aloud from your page. Without Speakable markup, they guess -and they frequently guess wrong, reading your cookie notice.

AI systems don't cite websites -they cite entities. A verifiable business with an address, named authors, and social proof. Our self-audit (88/100) still loses points here because we lack a physical address. That's how strict this criterion is.
