Weak AI visibility with 7 of 22 criteria passing. Biggest gap: llms.txt file.
Verdict
checkfragment.com is early-stage for AEO with an overall score of 31/100, despite strong canonical handling (10/10) and high fact density (8/10 with 171 quantitative points). The largest blockers are foundational machine-readability gaps: no llms.txt (0/10), no schema at all (0/10), no schema coverage depth (0/10), no RSS/Atom feed (0/10), and no AI licensing signals (0/10). Crawl support is partial rather than complete, with robots.txt present but no explicit AI crawler directives (5/10), and a sitemap that is valid but thin (9 URLs) and missing all lastmod dates (5/10; publishing velocity 2/10). Content exists at scale, but extractability is weak due to missing direct answer patterns (2/10), FAQ structure/schema gaps (2/10), and semantic/accessibility omissions like missing <main>, <article>, and <time> elements.

Guides for the criteria with the most room for improvement
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.
Tidio runs 4 JSON-LD schema types. Crisp runs zero. That's not a coincidence -it's the difference between a 63 and a 34. Structured data is the machine-readable layer AI trusts most.
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.
AI engines are citation machines -they need specific facts to quote. A page full of general advice with zero data points gives them nothing to work with.
