Improve AI search and crawler readiness
Why this needs attention
One or more AI discovery, user-fetch, indexability, snippet, synthetic reachability, or sitemap signals need attention.
AI search systems need crawlable, reachable, indexable, and quotable public content. Training and data-use choices remain neutral publisher preferences.

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

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.

Fix rendered axe accessibility violations
Why this needs attention
The rendered page has accessibility rule violations detected by axe-core.

Recommended correction
Evidence
axe found 9 violation rule(s); 9 non-contrast rule(s) are scored here, including 4 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 3 result(s) require review. Top rules: image-alt (1), link-name (2), list (1), listitem (6), landmark-no-duplicate-main (1).

Make the primary CTA obvious
Why this needs attention

Basic contrast
Why this needs attention
The scanner found text/background color pairs that may be hard to read, or could not verify contrast.
Low contrast makes a launch page feel less polished and can exclude users with low vision.

Hero clarity signals
Why this needs attention
One or more heading, introductory-copy, or next-action signals fell outside this heuristic's expected range; this does not by itself prove the page is vague.

Recommended correction
Evidence
Detected 0 H1 heading(s), 0 H1 characters, 0 introductory supporting-copy characters after excluding bylines and short labels, and 0 actionable CTA(s).

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.
