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 5: fix before sharing the page publicly.
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 2 violation rule(s); 2 non-contrast rule(s) are scored here, including 0 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 3 result(s) require review. Top rules: landmark-unique (2), image-redundant-alt (1).
Priority
Priority 5: fix before sharing the page publicly.
Affected elements
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination
Fix any of the following: The landmark must have a unique aria-label, aria-labelledby, or title to make landmarks distinguishable

Fix Prompt
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 100/100, answer-ready text 100/100, semantic structured data 97/100. Detected role: home (high confidence).
Priority
Priority 6: fix during launch polish.
Fix Prompt
Improve rendered speed signals
Why this needs attention
The browser-rendered page shows slow or heavy speed signals.
Slow pages lose impatient visitors and make every SEO, social, and paid-traffic visit work harder.

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.
