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.

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 1 image(s) with empty alt text that appear informative, out of 4. 0 empty-alt image(s) looked decorative and were not counted as failures.

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

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 2 violation rule(s); 1 non-contrast rule(s) are scored here, including 0 serious or critical rule(s). Color contrast is scored once by the dedicated contrast check. 2 result(s) require review. Top rules: color-contrast (14), region (3).

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.

Why this needs attention
The safe public scan could not inspect private or browser-set cookies, so cookie flag coverage was not verified.
Session and preference cookies should avoid unnecessary exposure before early users sign in or submit forms.

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
16 of 162 rendered text color sample(s) across captured viewports missed WCAG contrast targets. Worst rendered ratio: 1.06. Mobile 390px viewport: 14 of 156 failed; worst ratio 1.09:1. Failed: earned 0 of 8 points.

Rendered composition and spacing
Why this needs attention
Rendered geometry found cramped text, overly long lines, undersized body copy, or too many competing actions in the first viewport.
Consistent spacing helps the page feel deliberate and easier to scan.
Recommended correction
Evidence
Desktop 1366px: 8 unique above-fold action(s), 6 body sample(s) below 14px, 1 cramped line-height sample(s), and 2 overlong line sample(s). Mobile 390px: 6 unique above-fold action(s), 7 body sample(s) below 14px, 1 cramped line-height sample(s), and 0 overlong line sample(s). Repeated CTA labels are deduplicated and do not earn extra credit. More than three distinct actions compete in a captured first viewport. Failed: earned 2 of 7 points from partial coverage.

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 16px/700 weight versus a 14px/400 median body style (1.14× size). Captured 26 supporting heading(s) and 13 action(s). The main heading has a clear rendered emphasis over body copy. 16 of 162 rendered text samples missed contrast targets, so hierarchy is not considered fully legible.

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.
