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 20/100, answer-ready text 27/100, semantic structured data 0/100. Detected role: directory (high confidence).

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 6 violation rule(s); 6 non-contrast rule(s) are scored here, including 2 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 0 result(s) require review. Top rules: button-name (2), link-name (3), landmark-one-main (1), meta-viewport (1), region (55).

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

Visual hierarchy
Why this needs attention
Rendered typography, geometry, and contrast show that the main heading is not distinct or legible enough, or that the hierarchy needs manual review.
Hierarchy tells visitors what to read first and what action to take next.
Recommended correction
Evidence
The rendered H1 is 0px/400 weight versus a 16px/400 median body style (0× size). Captured 0 supporting heading(s) and 6 action(s). The main heading is only 0× the median body-text size with no meaningful weight increase, so it does not establish a clear first reading priority. 39 of 201 rendered text samples missed contrast targets, so hierarchy is not considered fully legible. Failed: earned 0 of 9 points.

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.
