Add common public security headers
Why this needs attention
Several basic browser protection headers were not visible.
These headers reduce avoidable browser-side risk and show a baseline of care before launch.
Recommended correction
Evidence
Detected 1 of 5 common public security controls. Present: strict-transport-security. Missing: content-security-policy, x-content-type-options, frame protection (x-frame-options or content-security-policy frame-ancestors), referrer-policy.

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 3 violation rule(s), including 1 serious or critical rule(s). Top rules: color-contrast (21), heading-order (1), image-redundant-alt (2).

Priority
Priority 4: fix before sharing the page publicly.
Fix Prompt
Shorten the meta description
Why this needs attention

Long descriptions are likely to be truncated or rewritten, which can hide the most useful part of the message.
Recommended correction
Evidence
Meta description is 238 characters, above the 170-character maximum.
Priority
Priority 3: fix before sharing the page publicly.
Fix Prompt

Basic contrast
Why this needs attention

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.
