Gatsby Website Audit

Gatsby audit: static HTML that still ships no-store and a fat runtime

· Configuration notes, not a newsroom.

SiteRune fingerprints ___gatsby. SSG should be the easy mode for TTFB. It often is not, because the host sends no-store or the page hydrates a SPA anyway.

What 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

Static is a build, not a Cache-Control

If the HTML is prebuilt and the CDN still says private, no-store, perf-cache fires. Fix the host headers. Do not rebuild Gatsby to solve a CDN misconfig.

The runtime is optional. Act like it.

Gatsby sites fail AEO when the visible content is client-only. Prefetch every internal link if you want; still put titles, schema, and llms.txt in the static HTML. Headers at the CDN. We are not going to recommend a new Gatsby plugin for HSTS.

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.
