Weak AI visibility with 6 of 22 criteria passing. Biggest gap: llms.txt file.
Verdict
ycombinator.com shows foundational crawl health but low overall AEO readiness at 32/100. Core machine-readable signals are missing: llms.txt (0/10, HTTP 404), Schema.org structured data (0/10), schema coverage depth (0/10), and canonical strategy (0/10). Content is indexable and navigable (internal linking 8/10, semantic HTML/accessibility 8/10, sitemap completeness 9/10), but answer extraction and freshness trust are weak (direct answer paragraphs 1/10, content freshness signals 2/10, publishing velocity 3/10 with all 81 URLs sharing lastmod 2026-02-23). The site has enough structural strength to improve quickly if it adds explicit AI, schema, and answer-first content signals.

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.
You published a great blog post in January. It's now February and nothing else has appeared. AI engines notice -and they're crawling less often because of it.
AI engines don't read your article top to bottom. They scan headings, grab the first 1-2 sentences underneath, and move on. If those sentences are throat-clearing preamble instead of a direct answer - you just lost a citation to someone who leads with the point.
