## What it does

Checks any website's AI citation readiness across 5 dimensions:

- **Structured Data** — JSON-LD schema markup
- **Meta Tags** — title, description, OpenGraph
- **Content Quality** — headings, word count, FAQ, citable sentences
- **Technical Config** — robots.txt, llms.txt, sitemap, speed
- **AI Signals** — speakable schema, statistics, direct-answer format

Returns a grade (A–F) and score (0–100) in under a second. No auth required.
