Biggest score-losing checks
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 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.
Priority
Priority 5: fix before sharing the page publicly.

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 5 violation rule(s), including 2 serious or critical rule(s). Top rules: color-contrast (12), link-name (9), landmark-unique (1), region (3), image-redundant-alt (1).

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.
Recommended correction
Evidence

Priority
Priority 14: fix during launch polish.
Load contributors
Asset timings are observed request durations. They are not added together because browsers can load requests in parallel.

Ready combines robots policy, a bounded synthetic User-Agent fetch, indexability, and snippet eligibility. Synthetic probes do not prove vendor-origin traffic. Purple 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.
