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
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 7 violation rule(s); 6 non-contrast rule(s) are scored here, including 4 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 1 result(s) require review. Top rules: image-alt (4), aria-hidden-focus (52), color-contrast (1), link-name (4), list (2).

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 70/100, answer-ready text 45/100, semantic structured data 0/100. 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 3 of 5 common public security controls. Present: strict-transport-security, content-security-policy, frame protection (x-frame-options). Missing: x-content-type-options, referrer-policy. Needs strengthening: content-security-policy only supplies a narrow control; add a default-src or script-src resource policy.
Priority

Fix Prompt
Add meaningful image alt text
Why this needs attention
One or more images are missing alt text.
People using screen readers may miss product context, trust signals, or calls to action.
Recommended correction
Evidence
Detected 0 image(s) with no alt attribute and 15 image(s) with empty alt text that appear informative, out of 29. 0 empty-alt image(s) looked decorative and were not counted as failures.

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
19 of 104 rendered text color sample(s) across captured viewports missed WCAG contrast targets. Worst rendered ratio: 2.77. Failed: earned 0 of 8 points.

Visible primary CTA
Why this needs attention
The page does not have a detectable call to action.
Early visitors need a clear next step, such as trying the product, joining a waitlist, or booking a demo.
Recommended correction
Evidence
Rendered CTA evidence: 0 desktop above-fold action(s) across 0 unique purpose(s); 2 mobile above-fold action(s) across 2 unique purpose(s). 0 repeated occurrence(s) were deduplicated and earned no extra credit. Failed: earned 7 of 14 points from partial coverage.

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.
The introduction should help visitors understand the purpose of this particular page.
Recommended correction
Evidence
Detected 1 visible H1 heading(s), 41 H1 characters, 0 introductory supporting-copy characters after excluding bylines and short labels, and 7 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). Failed: earned 9 of 13 points from partial coverage.

Fix Prompt
Visual hierarchy
Why this needs attention
Rendered typography, geometry, and contrast show that the main heading is not distinct or legible enough, or that the hierarchy needs manual review.
Hierarchy tells visitors what to read first and what action to take next.
Recommended correction
Evidence
The rendered H1 is 32px/700 weight versus a 16px/400 median body style (2× size). Captured 33 supporting heading(s) and 6 action(s). The main heading has a clear rendered emphasis over body copy. 19 of 104 rendered text samples missed contrast targets, so hierarchy is not considered fully legible. Failed: earned 6 of 9 points from partial coverage.

Rendered speed signals
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.
