# The Website Specification

> A platform-agnostic, full specification of the technical features a good website should have. Built in the open under an MIT licence.

An Open Knowledge Format bundle of 144 checks across 10 categories, derived from https://specification.website. Each check mirrors a spec page; the `references/` directory mirrors every cited standard. Content licensed CC BY 4.0; canonical pages live at https://specification.website/spec/.

## Categories

* [Foundations](foundations/index.md) - The HTML, head, and document basics every page needs.
* [SEO](seo/index.md) - Search visibility — robots.txt, sitemaps, canonicals, structured data.
* [Accessibility](accessibility/index.md) - WCAG-aligned rules so people of all abilities can use the site.
* [Security](security/index.md) - Headers, transport, and policies that keep visitors safe.
* [Well-Known URIs](well-known/index.md) - Standard, agreed-upon paths under /.well-known/.
* [Agent Readiness](agent-readiness/index.md) - Things that make a site legible to AI agents and crawlers.
* [Performance](performance/index.md) - Core Web Vitals, caching, images, fonts, network behaviour.
* [Privacy](privacy/index.md) - Consent, signals, and respecting visitor choice.
* [Resilience](resilience/index.md) - Graceful failure — error pages, offline, redirects.
* [Internationalisation](i18n/index.md) - Language, locale, direction, and translated content.

## Bundle

* [References](references/index.md) - Mirrored external standards.
* [Change log](log.md) - History of the spec, newest first.
