For your AI agent
Share this audit’s URL with ChatGPT, Claude, or your coding agent to turn findings into fixes. Your agent can open the saved evidence below when it needs more detail; these files never start a new scan.
Agent-readable files
Strengthen answer-engine content quality
Why this needs attention
The page is technically discoverable, but its entity clarity, answer-ready copy, structured data, evidence, authorship, or freshness is not yet complete.
Search and answer systems need clear, extractable, verifiable facts in addition to crawl access and metadata.
Recommended correction
Evidence
Role-aware AEO content components: entity clarity 35/100, answer-ready text 0/100, semantic structured data 0/100. Detected role: other (low confidence).
Priority
Priority 6: fix during launch polish.
Fix Prompt
Add common public security headers
Why this needs attention
Several browser protection headers are missing or present only as weak, narrow policies.
These headers reduce avoidable browser-side risk and show a baseline of care before launch.
Recommended correction
Evidence
Detected 0 of 5 common public security controls. Present: none. Missing: strict-transport-security, content-security-policy, x-content-type-options, frame protection (x-frame-options or content-security-policy frame-ancestors), referrer-policy. Needs strengthening: none.
Priority
Priority 5: fix before sharing the page publicly.
Fix Prompt
Publish a valid sitemap
Why this needs attention
The sitemap file was not reachable or did not look like valid sitemap XML.
A sitemap helps search engines discover the landing page and related public pages sooner.
Recommended correction
Evidence
HTTP 404 returned for sitemap_xml.
Priority
Priority 7: fix during launch polish.
Fix Prompt
Add a canonical URL
Why this needs attention
The page does not declare which public URL is the preferred version.
A canonical tag reduces duplicate URL confusion before marketing links start spreading.
Recommended correction
Evidence
Canonical does not align with the scanned page: https://knowbooks.com/s/heliX/index.html.
Priority
Priority 9: fix during launch polish.
Fix Prompt
Fix rendered axe accessibility violations
Why this needs attention
The rendered page has accessibility rule violations detected by axe-core.
axe checks the actual browser-rendered page, so these issues can affect people using keyboards, screen readers, or other assistive technology.
Recommended correction
Evidence
axe found 1 violation rule(s); 1 non-contrast rule(s) are scored here, including 0 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 0 result(s) require review. Top rules: region (4).

Text density
Why this needs attention
The page may not provide enough useful context for its detected role, or its rendered structure needs review.
Too little copy can leave visitors confused; too much copy can bury the value proposition.
Recommended correction
Evidence

Rendered composition and spacing
Why this needs attention
Rendered geometry found cramped text, overly long lines, undersized body copy, or too many competing actions in the first viewport.
Consistent spacing helps the page feel deliberate and easier to scan.
Recommended correction
Evidence
Desktop 1366px: 1 unique above-fold action(s), 2 body sample(s) below 14px, 0 cramped line-height sample(s), and 0 overlong line sample(s).

Ready combines robots policy, a bounded synthetic User-Agent fetch, indexability, and snippet eligibility. Synthetic probes do not prove vendor-origin traffic. Preference states are training or data-use choices and do not lower the AEO score.
The image refreshes from FreeScan after a completed rescan. Clicking it always opens the newest public report saved for this exact scanned URL.
Scan evidence is included as untrusted data. The implementation brief instructs agents to verify findings before editing and to avoid destructive or speculative changes.
