Remove insecure page resources
Why this needs attention
The page references insecure HTTP assets or links from an HTTPS page.
Mixed content can cause browser warnings, broken assets, and lower visitor trust.
Recommended correction
Evidence
Detected 1 insecure asset or link reference(s).
Priority
Priority 4: fix before sharing the page publicly.
Fix Prompt
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 55/100, answer-ready text 57/100, semantic structured data 73/100. Detected role: home (high confidence).
Priority
Priority 6: fix during launch polish.
Fix Prompt
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 4 of 5 common public security controls. Present: strict-transport-security, x-content-type-options, frame protection (x-frame-options), referrer-policy. Missing: content-security-policy. Needs strengthening: none.
Priority
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); 3 non-contrast rule(s) are scored here, including 0 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 1 result(s) require review. Top rules: landmark-one-main (1), page-has-heading-one (1), region (25).
Priority
Priority 5: fix before sharing the page publicly.
Affected elements
Document should have one main landmark
Fix all of the following: Document does not have a main landmark
Page should contain a level-one heading
Fix all of the following: Page must have a level-one heading
All page content should be contained by landmarks

Fix any of the following: Some page content is not contained by landmarks
All page content should be contained by landmarks

Fix any of the following: Some page content is not contained by landmarks
Fix Prompt
Review introductory 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.
The introduction should help visitors understand the purpose of this particular page.
Recommended correction
Evidence
Detected 0 visible H1 heading(s), 19 H1 characters, 0 introductory supporting-copy characters after excluding bylines and short labels, and 20 actionable CTA(s). Rendered evidence was used where available. The H1 text is treated as a subject label, so an appropriate short place, product, or page name does not lose points. Detected role: home (high confidence).

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.

Recommended correction
Evidence

Fix Prompt
Heading structure
Why this needs attention
The page heading structure is either missing a single main heading or skips heading levels.
Clear headings help visitors, search engines, and assistive technology understand the page quickly.
Recommended correction
Evidence
Detected 0 visible H1 heading(s) and 43 visible heading(s) in the rendered page. Heading-level order is assessed separately under Accessibility. Failed: earned 0 of 8 points.

Fix Prompt
Relevant schema coverage
Why this needs attention
The page is missing a primary JSON-LD entity that matches its actual role, or its named entity is not supported by visible content.
Structured data gives search and answer engines explicit facts about your product.
Recommended correction
Evidence
Detected 1 JSON-LD block(s). Primary types: CollectionPage, Organization, Place, WebSite. A primary type matches the page role. The named entity was not clearly supported by visible page content. Failed: earned 7 of 10 points from partial coverage.

Priority 12: fix during launch polish.
Fix Prompt
Schema quality and validity
Why this needs attention
The JSON-LD may parse, but its required facts, page-role relevance, visible-content agreement, or graph connections are incomplete.
Invalid structured data can be ignored by search and answer systems, even when visible page content is strong.
Recommended correction
Evidence
1 of 1 JSON-LD block(s) parsed. Semantic quality is 73/100: completeness 71/100, graph connectivity 90/100, primary types CollectionPage, Organization, Place, WebSite, currently useful search-feature types Organization, WebSite. Nested types do not count as separate schema coverage. SearchAction is retired as a Google search feature and earns no coverage credit. Failed: earned 7 of 8 points from partial coverage.

Common security headers
Why this needs attention
Several browser protection headers are missing or present only as weak, narrow policies.

Recommended correction
Evidence
Detected 4 of 5 common public security controls. Present: strict-transport-security, x-content-type-options, frame protection (x-frame-options), referrer-policy. Missing: content-security-policy. Needs strengthening: none. Failed: earned 12 of 18 points from partial coverage.

Fix Prompt
Landmark presence
Why this needs attention
The page is missing common landmarks such as header, nav, main, or footer.
Landmarks make the page easier to navigate for assistive technology and keyboard users.
Recommended correction
Evidence
Detected 0 visible main landmark(s) and 0 visible landmark element(s) or roles. A page should expose one main landmark. Failed: earned 0 of 10 points.

Priority 18: lower-risk cleanup after urgent launch blockers.
Fix Prompt
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.
Recommended correction
Evidence
2 of 116 rendered text color sample(s) across captured viewports missed WCAG contrast targets. Worst rendered ratio: 1. Mobile 390px viewport: 0 of 18 failed. Failed: earned 0 of 8 points.

Readability signals
Why this needs attention
The sampled prose exceeds the average sentence-length threshold; this is a reading-effort signal, not a complete readability assessment.
Launch visitors often skim; long sentences make the offer harder to understand.
Recommended correction
Evidence
Average prose sentence length is about 30 word(s), measured from 90 words across 3 sentences in 2 text block(s). Paragraph boundaries are preserved; navigation, card labels, bylines, and controls are excluded. Failed: earned 0 of 9 points.

Rendered layout ergonomics
Why this needs attention
The browser-rendered page has layout or tap-target issues.
Horizontal overflow and tiny tap targets make the page feel broken on real devices, especially for mobile visitors.
Recommended correction
Evidence
Desktop horizontal overflow: 17px. Mobile horizontal overflow at 390px: 810px. WCAG 2.2 AA target-size failures: 0. Targets smaller than 24×24px pass only when the required spacing or another WCAG exception applies. 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.
