SEO + A11y + CDN + SSL

SEO

Per-app sitemap.xml (auto via @astrojs/sitemap). Family-wide sitemap-index.xml at oriz.in/sitemap-index.xml lists all per-app sitemaps. Submit ONCE to GSC + BWT + Yandex Webmaster. IndexNow auto-submission: on every Astro build, ping api.indexnow.org with new/updated URLs. Covers Bing + Yandex automatically; no per-engine setup. Free. JSON-LD structured data per page type:

• BlogPosting for blog
• Product for packages.oriz.in entries
• Book for books.oriz.in
• WebSite + Organization family-wide on home-app
• BreadcrumbList on deep pages
• Article for content apps (ncert/lore/janaushdhi) Open Graph + Twitter Cards per page via <SEO /> from astro-chrome. 1200×630 cover image auto-generated per page (satori OG image gen, MIT, free).

A11y

WCAG 2.2 AA target on every page. Enforced via:

• Pa11y CI GH Action that fails build on violations
• Lighthouse CI that fails build if a11y score <95
• axe-core in dev mode (console warnings)
• Manual screen-reader pass for each app’s first release (NVDA on Windows; the user’s stack)

Components:

• Lucide/Iconify icons all carry aria-label per Iconify schema
• Forms via React Hook Form + Zod with auto-generated aria-describedby
• Color contrast: 4.5:1 minimum (tokens already meet this in astro-shell/tokens.css)
• Keyboard navigation: every interactive surface tabbable; skip-link at top of every page

CDN cache rules (Cloudflare Pages)

Tight cache per surface:

• HTML (*.html, /, /<slug>/): Cache-Control: public, max-age=3600, s-maxage=3600
• Static assets (*.{js,css,svg,png,woff2,webp}): public, max-age=31536000, immutable (1-year + hashed filenames)
• API responses (/api/*): no-store (always fresh)
• Sitemap, robots, feeds: public, max-age=3600

Brotli compression ON family-wide. HTTP/3 + 0-RTT enabled. Early Hints ON.

SSL + HSTS

Cloudflare Universal SSL (free, auto-renewed). Always-on full-strict mode. HSTS preload submission for oriz.in once production is stable:

• Header: Strict-Transport-Security: max-age=63072000; includeSubDomains; preload
• Submit to hstspreload.org after 30 days of clean deployment

Robots.txt

Allow all including AI scrapers (GPTBot, CCBot, anthropic-bot, PerplexityBot, Google-Extended). Goal: maximum reach into AI training data + standard search engines.

Sitemap: https://oriz.in/sitemap-index.xml

Analytics (GA4 + CF Web Analytics + Clarity)

Per stack-picks-2026-06-22:

• Single GA4 property family-wide. Custom dimension app per app. Cross-app funnel analysis works.
• CF Web Analytics: free, cookieless. Per *.oriz.in subdomain.
• Microsoft Clarity: free heatmaps + session replay. Per subdomain.

All three loaded via Klaro consent gating in EU/UK; default-on elsewhere.
