Why this matters
Alt text is what a screen reader announces, and what image search and AI systems read in place of the picture. This check does not apply to the features observed in this sample.

No frame-embedding restriction was observed (neither CSP frame-ancestors nor X-Frame-Options).
Why this matters
HTTPS protects what visitors send you, and response headers limit what a hostile page can do in their browser. It is there, but weaker than this check expects.
Recommended fix
Send Content-Security-Policy: frame-ancestors 'self' (or 'none', or a list of partner origins), or X-Frame-Options: SAMEORIGIN. It stops other sites from framing your pages to trick visitors into clicking (clickjacking).

Why this matters
HTTPS protects what visitors send you, and response headers limit what a hostile page can do in their browser. It is there, but weaker than this check expects.
Recommended fix
Add it — one header, stops MIME-sniffing attacks. Most hosts let you set headers in config (vercel.json, netlify.toml, next.config).

The X-Powered-By header advertises "Next.js".
Why this matters
HTTPS protects what visitors send you, and response headers limit what a hostile page can do in their browser. It is there, but weaker than this check expects.
Recommended fix
You can remove it (in Next.js: poweredByHeader: false; in Express: app.disable('x-powered-by')). It adds bytes to every response and tells scanners what to probe; it is not a vulnerability by itself.

AI answer readiness
Retrieval signals an answer engine relies on: crawler access, clear entities and answers it can quote. These checks do not measure citations or traffic.
Could be better: FAQ/QA schemaNo FAQPage or QAPage schema on any crawled page.
Could be better · AI answer readiness · Review suggested
Observed evidence
No FAQPage or QAPage schema on any crawled page.
Why this matters
This is what an AI assistant relies on when deciding whether it can quote your page. It is there, but weaker than this check expects.
Recommended fix
If the page answers recurring questions, use visible question-and-answer content and matching FAQPage markup. QAPage is for a single question with user-submitted answers. Google FAQ rich results are restricted to eligible authoritative government and health sites; markup does not guarantee AI citations.
Could be better: Freshness signalsNo dateModified schema or visible 'updated' dates found.
Could be better · AI answer readiness · Review suggested
Observed evidence
No dateModified schema or visible 'updated' dates found.
Why this matters
This is what an AI assistant relies on when deciding whether it can quote your page. It is there, but weaker than this check expects.
Recommended fix
For content where dates matter, show the actual update date and mirror it in dateModified. Do not invent dates or change them without a substantive update. Missing dates alone do not prove stale content.
Could be better: Question headings have concise answers41/77 question-shaped heading(s) have a 20–500 character paragraph immediately after them.
Could be better · AI answer readiness · Measured on your page
Observed evidence
41/77 question-shaped heading(s) have a 20–500 character paragraph immediately after them.
Why this matters
This is what an AI assistant relies on when deciding whether it can quote your page. It is there, but weaker than this check expects.
Recommended fix
Put a direct 20–500 character answer paragraph immediately after each question heading so retrieval systems can quote it cleanly.

Why this matters
This is what an AI assistant relies on when deciding whether it can quote your page. It is there, but weaker than this check expects.
Recommended fix
Publish a clean markdown copy of each key page at /page.md (or /page.html.md). It strips navigation and scripts, so a retriever spends its budget on your content.

AdSense readinessOptional
Publisher-policy signals, for sites that plan to carry ads. These checks do not affect the overall score or grade, and they do not measure or guarantee AdSense approval.

1/6 editorial pages expose fewer than 250 publisher words; those 6 pages hold 27053 publisher words in total. 4 of the 10 sampled pages are support or tool pages and were excluded from this check.
Why this matters
A publisher review looks for this before it accepts a site. It is there, but weaker than this check expects.
