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 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. Needs strengthening: none.
Priority
Priority 5: fix before sharing the page publicly.
Fix Prompt

The meta description is 184 characters, so it is longer than the recommended maximum.
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 184 characters, above the 170-character maximum.

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.
