A pillar guide to the 9 categories — what they cover, why they matter, and what counts as healthy.

Infrastructure, Bots & DNS
The delivery layer beneath the page: TLS, edge AI-bot handling, DNS, compression and headers.

Content Structure & Quality
Title, meta, headings, depth and how cleanly the main content can be isolated and read.
Structured Data
JSON-LD, entity & sameAs markup, recommended schema types, Open Graph — the machine-readable layer AI quotes.
