Astro Website Audit
Astro audit: islands, adapters, and HTML that should already be thin
· Configuration notes, not a newsroom.
Astro fingerprints from astro-island and the generator. SiteRune expects server-rendered HTML. Islands that hide the hero from the first response still fail.
ASWhat SiteRune checks on this stack
- CMS / framework fingerprint from HTML, headers, cookies, and generator tags — fingerprint-based, not a plugin inventory
- Titles, meta descriptions, canonicals, H1, and robots on the homepage and walked interiors
- Security headers a crawler can see: HTTPS, HSTS, CSP, framing, nosniff, Referrer-Policy, Permissions-Policy
- HTML TTFB, compression, and Cache-Control on the document — not a Lighthouse filmstrip
- AI-bot robots policy, llms.txt, and Organization / FAQ / Article JSON-LD
Common problems
- Marketing homepage looks finished; interior templates ship empty titles or leftover noindex
- Hosted CMS cannot set HSTS/CSP, so the brief tells you to put a proxy in front instead of inventing an admin UI
- A security plugin's 'block AI' preset Disallows GPTBot on a site that wanted citations
- Session cookies or no-store on every anonymous GET, so the CDN never caches HTML
Zero JS is the point. Use it.
If the marketing page is an island that fetches copy on the client, you threw away the framework. SiteRune reads the first HTML. generate metadata in frontmatter or the adapter equivalent. Ship /llms.txt as a static file.
Adapter headers
Netlify, Cloudflare, Node — headers live in the adapter config or the reverse proxy. We will not assume Vercel. nginx snippet still ships when headers are missing. Astro on Cloudflare is not Next.js.
FAQ
How do you know this is my stack?
Fingerprints in HTML, headers, cookies, and generator tags. Confidence is a score, not a certificate. Unknown stacks stay generic — we will not invent a CMS.
