- Score impact: 18 rule points lost.
- Evidence: Detected 0 of 5 common public security headers. Present: none. Missing: strict-transport-security, content-security-policy, x-content-type-options, x-frame-options, referrer-policy.
- What needs attention: Several basic browser protection headers were not visible.
- Why it matters: These headers reduce avoidable browser-side risk and show a baseline of care before launch.
- Status-specific guidance: A public check reported a failure. Reproduce or inspect the issue first, then make the smallest safe fix.
- Audience or recipient: The site owner, builder, or marketing team responsible for improving this public page.
- Constraints, examples, or source material: Treat the live URL as the public target to inspect, not as the only source of truth. When repository, CMS, or hosting access is available, use that implementation context before changing anything.
- Target outcome: After the fix is deployed and the public page is rescanned, this specific check should improve or pass without lowering other SEO / AEO, security, accessibility, or design signals.
## Task
Use the provided context to safely complete this workflow: Configure headers such as Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
Before editing, identify the likely source of the issue, the smallest change that can fix it, and any user-visible behavior that must be preserved.
## Output
Return a structured response with headings, prioritized recommendations, changed files or page areas, verification results, rollback notes, and stated assumptions.
## Rules
- Ask a clarifying question when required context is missing.
- Preserve the user's intent and avoid inventing facts.
- Verify the issue exists before changing code or content. If the issue is not reproducible, explain what you checked and recommend no code change.
- If the live URL and implementation source disagree, trust the implementation source for edits and use the live URL only to understand current public behavior.
- Keep the change narrowly scoped to this fix unless another change is required to avoid a regression.
- Match the existing framework, style, design system, routing patterns, and content conventions.
- Preserve existing URLs, forms, analytics, SEO metadata, accessibility semantics, and conversion flows unless the fix explicitly requires changing them.
- Do not perform broad refactors, dependency upgrades, redesigns, rewrites, migrations, file deletions, route changes, or destructive commands unless they are explicitly required and approved.
- Make changes that are easy to review and roll back.
- Verify the result with the smallest reliable test, build, browser check, or manual inspection available.
## Safety
- Do not request, expose, or reproduce sensitive data.
- Redact private details from examples unless the user explicitly says they are safe to include.
- Do not use credentials, cookies, authenticated data, hidden form values, or private response bodies.
- Do not weaken security headers, authentication, authorization, privacy controls, accessibility, or error handling to make the scan pass.

- Evidence: Heading levels found: 1, 2, 3, 3, 3, 3, 3, 3, 3, 2, 2, 3, 3, 3, 2, 3, 3, 3, 3, 3, 3, 2, 2, 2, 4, 4.
- What needs attention: Heading levels appear to jump or start without a clear hierarchy.
- Why it matters: A clean heading outline helps visitors scan the page and helps assistive technology navigate it.
- Status-specific guidance: A public check reported a failure. Reproduce or inspect the issue first, then make the smallest safe fix.
- Audience or recipient: The site owner, builder, or marketing team responsible for improving this public page.
- Constraints, examples, or source material: Treat the live URL as the public target to inspect, not as the only source of truth. When repository, CMS, or hosting access is available, use that implementation context before changing anything.
- Target outcome: After the fix is deployed and the public page is rescanned, this specific check should improve or pass without lowering other SEO / AEO, security, accessibility, or design signals.
## Task
Use the provided context to safely complete this workflow: Use headings in order: one H1, then H2 for major sections, then H3 for subsections.
Before editing, identify the likely source of the issue, the smallest change that can fix it, and any user-visible behavior that must be preserved.
## Output
Return a structured response with headings, prioritized recommendations, changed files or page areas, verification results, rollback notes, and stated assumptions.
## Rules
- Ask a clarifying question when required context is missing.
- Preserve the user's intent and avoid inventing facts.
- Verify the issue exists before changing code or content. If the issue is not reproducible, explain what you checked and recommend no code change.
- If the live URL and implementation source disagree, trust the implementation source for edits and use the live URL only to understand current public behavior.
- Keep the change narrowly scoped to this fix unless another change is required to avoid a regression.
- Match the existing framework, style, design system, routing patterns, and content conventions.
- Preserve existing URLs, forms, analytics, SEO metadata, accessibility semantics, and conversion flows unless the fix explicitly requires changing them.
- Do not perform broad refactors, dependency upgrades, redesigns, rewrites, migrations, file deletions, route changes, or destructive commands unless they are explicitly required and approved.
- Make changes that are easy to review and roll back.
- Verify the result with the smallest reliable test, build, browser check, or manual inspection available.
## Safety
- Do not request, expose, or reproduce sensitive data.
- Redact private details from examples unless the user explicitly says they are safe to include.
- Do not use credentials, cookies, authenticated data, hidden form values, or private response bodies.
- Do not weaken security headers, authentication, authorization, privacy controls, accessibility, or error handling to make the scan pass.

## Launch Readiness

Close to ready (Needs polish).

Passed: 31. Failed: 7. Unknown: 0.
Strongest area: SEO / AEO. Weakest area: Accessibility.

## Prioritized Fixes

### 1. Add common public security headers

- Category: Security
- Status: fail
- Severity: high
- Rule points lost: 18
- Evidence: Detected 0 of 5 common public security headers. Present: none. Missing: strict-transport-security, content-security-policy, x-content-type-options, x-frame-options, referrer-policy.
- Why it matters: These headers reduce avoidable browser-side risk and show a baseline of care before launch.
- Fix: Configure headers such as Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.

### 2. Fix rendered axe accessibility violations

- Category: Accessibility
- Status: fail
- Severity: high
- Rule points lost: 18
- Evidence: axe found 2 violation rule(s), including 1 serious or critical rule(s). Top rules: color-contrast (8), heading-order (1).
- Why it matters: axe checks the actual browser-rendered page, so these issues can affect people using keyboards, screen readers, or other assistive technology.
- Fix: Fix the top axe rule IDs first, especially critical and serious violations around names, roles, labels, headings, contrast, landmarks, and keyboard-accessible controls.

### 3. Fix heading order

- Category: Accessibility
- Status: fail
- Severity: medium
- Rule points lost: 11
- Evidence: Heading levels found: 1, 2, 3, 3, 3, 3, 3, 3, 3, 2, 2, 3, 3, 3, 2, 3, 3, 3, 3, 3, 3, 2, 2, 2, 4, 4.
- Why it matters: A clean heading outline helps visitors scan the page and helps assistive technology navigate it.
- Fix: Use headings in order: one H1, then H2 for major sections, then H3 for subsections.

### 4. Use one clear H1 and ordered headings

- Category: SEO / AEO
- Status: fail
- Severity: medium
- Rule points lost: 8
- Evidence: Detected 1 H1 heading(s) and 26 total headings.
- Why it matters: Clear headings help visitors, search engines, and assistive technology understand the page quickly.
- Fix: Keep one H1 for the main promise, then use H2 and H3 headings in order for sections below it.

### 5. Fix rendered layout ergonomics

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 9
- Evidence: Horizontal overflow: 0px. Small tap targets: 28.
- Why it matters: Horizontal overflow and tiny tap targets make the page feel broken on real devices, especially for mobile visitors.
- Fix: Remove elements wider than the viewport, add responsive constraints, and make important links, buttons, inputs, and controls at least 40px tall and wide where possible.

## Opportunities

### Add answer-ready sections for common buyer questions

- Impact: high
- Category: SEO / AEO
- Evidence: Pricing signals: 1. Use-case signals: 0. Integration/API signals: 0.
- Why it matters: Answer engines and search visitors need concise textual answers to summarize who the product is for, how it works, what it costs, and what it connects with.
- Next step: Add short, crawlable sections for pricing or plans, ideal users, use cases, integrations, security, and how the product differs from alternatives.

### Review snippet and preview controls

- Impact: low
- Category: SEO / AEO
- Evidence: Open Graph image was detected. Preview controls detected: 0.
- Why it matters: Preview controls can clarify how much text, image, and video content search systems may show from the page.
- Next step: Only add robots preview controls when you intentionally want to limit snippets or image/video previews; otherwise leave previews open.

### Tighten the live color system

- Impact: high
- Category: Accessibility
- Evidence: 4 of 100 rendered contrast sample(s) missed target. Worst ratio: 2.69.
- Why it matters: Computed contrast catches the actual colors visitors see after CSS, themes, and overlays are applied.
- Next step: Audit foreground/background token pairs for body text, muted text, links, buttons, inputs, and badges, then raise weak pairs to WCAG AA contrast targets.

### Polish rendered responsive ergonomics

- Impact: medium
- Category: Design
- Evidence: Horizontal overflow: 0px. Small tap targets: 28.
- Why it matters: Overflow and tiny controls are easy for static scans to miss but obvious to real users, especially on mobile and tablet layouts.
- Next step: Constrain wide elements, avoid fixed-width content that exceeds the viewport, and increase touch target sizes for interactive controls.

### Measure search performance with first-party data

- Impact: medium
- Category: SEO / AEO
- Evidence: robots.txt and sitemap.xml were reachable, so the site has the basics needed for Search Console verification and monitoring.
- Why it matters: A scan can identify technical readiness, but Search Console and analytics reveal impressions, queries, clicks, pages, and conversions over time.
- Next step: Verify the domain in Search Console, submit the sitemap, and pair query/page data with analytics events for signups, demo requests, and purchases.

## Insights

### The page appears basically crawlable

- Category: SEO / AEO
- Evidence: HTTP 200. robots.txt: HTTP 200. sitemap.xml: HTTP 200. noindex check: clear.
- Interpretation: The public page satisfies the basic crawl/index path the scan can verify.
- Recommended use: Use this as the first launch gate before deeper content, ranking, or AI visibility work.

### AEO depends on normal SEO plus answerable text

- Category: SEO / AEO
- Evidence: Visible words: 1194. H1 count: 1. Audience signals: 14. CTA labels: Start here How to Remember What You Read The full system: why highlighting fails, what active recall does, and how to keep a book's ideas for years in five minutes a day. Read the guide →, The science Why You Forget What You Read The forgetting curve, explained: what happens to a book in your brain over 30 days, and the one intervention that changes the slope. Read the guide →, The shortcut Turn Any Book Into Flashcards Making book flashcards by hand takes hours per book. Here's how to get a quality deck from just the title, in seconds. Read the guide →, The comparison Do Book Summary Apps Work? Summaries compress books you haven't read. Retention tools keep the ones you have. Which problem do you actually have? Read the guide →.
- Interpretation: Google AI features currently rely on standard Search eligibility; the extra advantage comes from content that is easy to quote, summarize, and verify.
- Recommended use: Prioritize clear text answers, crawlable support pages, accurate schema, and visible proof over speculative AI-only markup.

### Detected entity signals

- Category: SEO / AEO
- Evidence: Title: Kern — Remember What You Read | Spaced Repetition for Books. H1: Stop forgetting what you read.. Schema types: FAQPage, MobileApplication, VideoObject.
- Interpretation: The stronger and more consistent these entity signals are, the easier it is for search and answer systems to identify the brand, product category, and page purpose.
- Recommended use: Keep the title, H1, meta description, Open Graph, schema, footer, and about/pricing/docs pages aligned around the same product facts.

### Structured data is present

- Category: SEO / AEO
- Evidence: JSON-LD blocks: 3. Types: FAQPage, MobileApplication, VideoObject. Parse errors: 0.
- Interpretation: The page exposes machine-readable facts, but quality still depends on whether those facts match visible content.
- Recommended use: Validate JSON-LD and use only accurate facts that are visible or clearly supported on the public page.

### Weakest score area

- Category: Accessibility
- Evidence: SEO / AEO: 93/100. Security: 76/100. Accessibility: 61/100. Design: 85/100
- Interpretation: The weakest area is Accessibility, so improvements there should have the most visible effect on readiness.
- Recommended use: Use the score mix to choose the next workstream instead of treating every issue as equally urgent.

### LLM-readable file found

- Category: SEO / AEO
- Evidence: https://kern.cards/llms.txt returned HTTP 200.
- Interpretation: llms.txt can be a useful optional summary for agents, but it should not be treated as a guaranteed AI search ranking factor.
- Recommended use: Invest first in crawlability, helpful visible content, internal links, and accurate schema; add llms.txt as a tidy supplement.

### Rendered page experience snapshot

- Category: Design
- Evidence: Rendered text samples: 100. Contrast failures: 4. Console errors: 0. Horizontal overflow: 0px.
- Interpretation: The scan inspected the browser-rendered page, so contrast, runtime, layout, and timing signals are more representative than static markup alone.
- Recommended use: Use rendered checks to prioritize issues that visitors actually experience after JavaScript and CSS load.

### Rendered speed snapshot

- Category: Design
- Evidence: DOMContentLoaded: 339ms. Load complete: 399ms. First contentful paint: 452ms. Resources: 12. Scripts: 1. Images: 8. Third-party origins: 2. Transfer: not available.
- Interpretation: These are lightweight browser timings from one rendered scan, so they are useful directional signals rather than real-user performance proof.
- Recommended use: Use slow timings, high script counts, heavy transfer size, and many third-party origins to choose focused speed work, then verify important changes with analytics or field data when available.

### Rendered axe accessibility snapshot

- Category: Accessibility
- Evidence: axe violations: 2. Critical: 0. Serious: 1. Top rules: color-contrast, heading-order.
- Interpretation: axe-core catches common accessibility failures in the actual rendered DOM, but it is still automated coverage and not a full manual accessibility audit.
- Recommended use: Treat critical and serious axe failures as high-priority fixes, then manually review keyboard flow, focus states, screen reader meaning, and interaction states.

## Scope

FreeScan.app performs safe public checks only. It is not a penetration test, full SEO engagement, full accessibility audit, WCAG certification, backlink audit, rank tracker, or analytics platform.

Public reports expose the scanned public URL, safe scores, sanitized public evidence, and fix guidance. They do not include credentials, cookies, hidden form values, or sensitive response bodies.

Rescan same URL

- Evidence: 4 of 100 rendered text color sample(s) missed WCAG contrast targets. Worst rendered ratio: 2.69.
- What needs attention: The scanner found text/background color pairs that may be hard to read, or could not verify contrast.
- Why it matters: Low contrast makes a launch page feel less polished and can exclude users with low vision.
- Status-specific guidance: A public check reported a failure. Reproduce or inspect the issue first, then make the smallest safe fix.
- Audience or recipient: The site owner, builder, or marketing team responsible for improving this public page.
- Constraints, examples, or source material: Treat the live URL as the public target to inspect, not as the only source of truth. When repository, CMS, or hosting access is available, use that implementation context before changing anything.
- Target outcome: After the fix is deployed and the public page is rescanned, this specific check should improve or pass without lowering other SEO / AEO, security, accessibility, or design signals.
## Task
Use the provided context to safely complete this workflow: Review key text, buttons, and links against a 4.5:1 contrast target for normal text.
Before editing, identify the likely source of the issue, the smallest change that can fix it, and any user-visible behavior that must be preserved.
## Output
Return a structured response with headings, prioritized recommendations, changed files or page areas, verification results, rollback notes, and stated assumptions.
## Rules
- Ask a clarifying question when required context is missing.
- Preserve the user's intent and avoid inventing facts.
- Verify the issue exists before changing code or content. If the issue is not reproducible, explain what you checked and recommend no code change.
- If the live URL and implementation source disagree, trust the implementation source for edits and use the live URL only to understand current public behavior.
- Keep the change narrowly scoped to this fix unless another change is required to avoid a regression.
- Match the existing framework, style, design system, routing patterns, and content conventions.
- Preserve existing URLs, forms, analytics, SEO metadata, accessibility semantics, and conversion flows unless the fix explicitly requires changing them.
- Do not perform broad refactors, dependency upgrades, redesigns, rewrites, migrations, file deletions, route changes, or destructive commands unless they are explicitly required and approved.
- Make changes that are easy to review and roll back.
- Verify the result with the smallest reliable test, build, browser check, or manual inspection available.
## Safety
- Do not request, expose, or reproduce sensitive data.
- Redact private details from examples unless the user explicitly says they are safe to include.
- Do not use credentials, cookies, authenticated data, hidden form values, or private response bodies.
- Do not weaken security headers, authentication, authorization, privacy controls, accessibility, or error handling to make the scan pass.

Horizontal overflow: 0px. Small tap targets: 28.

Failed: earned 0 of 9 points.

Priority: Priority 13: fix during launch polish.

Why it matters: Horizontal overflow and tiny tap targets make the page feel broken on real devices, especially for mobile visitors.

Fix: Remove elements wider than the viewport, add responsive constraints, and make important links, buttons, inputs, and controls at least 40px tall and wide where possible.

- Accessibility: 61/100
- Design: 85/100

## Launch Readiness

Close to ready (Needs polish).

Passed: 31. Failed: 7. Unknown: 0.
Strongest area: SEO / AEO. Weakest area: Accessibility.

## Prioritized Fixes

### 1. Add common public security headers

- Category: Security
- Status: fail
- Severity: high
- Rule points lost: 18
- Evidence: Detected 0 of 5 common public security headers. Present: none. Missing: strict-transport-security, content-security-policy, x-content-type-options, x-frame-options, referrer-policy.
- Why it matters: These headers reduce avoidable browser-side risk and show a baseline of care before launch.
- Fix: Configure headers such as Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.

### 2. Fix rendered axe accessibility violations

- Category: Accessibility
- Status: fail
- Severity: high
- Rule points lost: 18
- Evidence: axe found 2 violation rule(s), including 1 serious or critical rule(s). Top rules: color-contrast (8), heading-order (1).
- Why it matters: axe checks the actual browser-rendered page, so these issues can affect people using keyboards, screen readers, or other assistive technology.
- Fix: Fix the top axe rule IDs first, especially critical and serious violations around names, roles, labels, headings, contrast, landmarks, and keyboard-accessible controls.

### 3. Fix heading order

- Category: Accessibility
- Status: fail
- Severity: medium
- Rule points lost: 11
- Evidence: Heading levels found: 1, 2, 3, 3, 3, 3, 3, 3, 3, 2, 2, 3, 3, 3, 2, 3, 3, 3, 3, 3, 3, 2, 2, 2, 4, 4.
- Why it matters: A clean heading outline helps visitors scan the page and helps assistive technology navigate it.
- Fix: Use headings in order: one H1, then H2 for major sections, then H3 for subsections.

### 4. Use one clear H1 and ordered headings

- Category: SEO / AEO
- Status: fail
- Severity: medium
- Rule points lost: 8
- Evidence: Detected 1 H1 heading(s) and 26 total headings.
- Why it matters: Clear headings help visitors, search engines, and assistive technology understand the page quickly.
- Fix: Keep one H1 for the main promise, then use H2 and H3 headings in order for sections below it.

### 5. Fix rendered layout ergonomics

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 9
- Evidence: Horizontal overflow: 0px. Small tap targets: 28.
- Why it matters: Horizontal overflow and tiny tap targets make the page feel broken on real devices, especially for mobile visitors.
- Fix: Remove elements wider than the viewport, add responsive constraints, and make important links, buttons, inputs, and controls at least 40px tall and wide where possible.

## Opportunities

### Add answer-ready sections for common buyer questions

- Impact: high
- Category: SEO / AEO
- Evidence: Pricing signals: 1. Use-case signals: 0. Integration/API signals: 0.
- Why it matters: Answer engines and search visitors need concise textual answers to summarize who the product is for, how it works, what it costs, and what it connects with.
- Next step: Add short, crawlable sections for pricing or plans, ideal users, use cases, integrations, security, and how the product differs from alternatives.

### Review snippet and preview controls

- Impact: low
- Category: SEO / AEO
- Evidence: Open Graph image was detected. Preview controls detected: 0.
- Why it matters: Preview controls can clarify how much text, image, and video content search systems may show from the page.
- Next step: Only add robots preview controls when you intentionally want to limit snippets or image/video previews; otherwise leave previews open.

### Tighten the live color system

- Impact: high
- Category: Accessibility
- Evidence: 4 of 100 rendered contrast sample(s) missed target. Worst ratio: 2.69.
- Why it matters: Computed contrast catches the actual colors visitors see after CSS, themes, and overlays are applied.
- Next step: Audit foreground/background token pairs for body text, muted text, links, buttons, inputs, and badges, then raise weak pairs to WCAG AA contrast targets.

### Polish rendered responsive ergonomics

- Impact: medium
- Category: Design
- Evidence: Horizontal overflow: 0px. Small tap targets: 28.
- Why it matters: Overflow and tiny controls are easy for static scans to miss but obvious to real users, especially on mobile and tablet layouts.
- Next step: Constrain wide elements, avoid fixed-width content that exceeds the viewport, and increase touch target sizes for interactive controls.

### Measure search performance with first-party data

- Impact: medium
- Category: SEO / AEO
- Evidence: robots.txt and sitemap.xml were reachable, so the site has the basics needed for Search Console verification and monitoring.
- Why it matters: A scan can identify technical readiness, but Search Console and analytics reveal impressions, queries, clicks, pages, and conversions over time.
- Next step: Verify the domain in Search Console, submit the sitemap, and pair query/page data with analytics events for signups, demo requests, and purchases.

## Insights

### The page appears basically crawlable

- Category: SEO / AEO
- Evidence: HTTP 200. robots.txt: HTTP 200. sitemap.xml: HTTP 200. noindex check: clear.
- Interpretation: The public page satisfies the basic crawl/index path the scan can verify.
- Recommended use: Use this as the first launch gate before deeper content, ranking, or AI visibility work.

### AEO depends on normal SEO plus answerable text

- Category: SEO / AEO
- Evidence: Visible words: 1194. H1 count: 1. Audience signals: 14. CTA labels: Start here How to Remember What You Read The full system: why highlighting fails, what active recall does, and how to keep a book's ideas for years in five minutes a day. Read the guide →, The science Why You Forget What You Read The forgetting curve, explained: what happens to a book in your brain over 30 days, and the one intervention that changes the slope. Read the guide →, The shortcut Turn Any Book Into Flashcards Making book flashcards by hand takes hours per book. Here's how to get a quality deck from just the title, in seconds. Read the guide →, The comparison Do Book Summary Apps Work? Summaries compress books you haven't read. Retention tools keep the ones you have. Which problem do you actually have? Read the guide →.
- Interpretation: Google AI features currently rely on standard Search eligibility; the extra advantage comes from content that is easy to quote, summarize, and verify.
- Recommended use: Prioritize clear text answers, crawlable support pages, accurate schema, and visible proof over speculative AI-only markup.

### Detected entity signals

- Category: SEO / AEO
- Evidence: Title: Kern — Remember What You Read | Spaced Repetition for Books. H1: Stop forgetting what you read.. Schema types: FAQPage, MobileApplication, VideoObject.
- Interpretation: The stronger and more consistent these entity signals are, the easier it is for search and answer systems to identify the brand, product category, and page purpose.
- Recommended use: Keep the title, H1, meta description, Open Graph, schema, footer, and about/pricing/docs pages aligned around the same product facts.

### Structured data is present

- Category: SEO / AEO
- Evidence: JSON-LD blocks: 3. Types: FAQPage, MobileApplication, VideoObject. Parse errors: 0.
- Interpretation: The page exposes machine-readable facts, but quality still depends on whether those facts match visible content.
- Recommended use: Validate JSON-LD and use only accurate facts that are visible or clearly supported on the public page.

### Weakest score area

- Category: Accessibility
- Evidence: SEO / AEO: 93/100. Security: 76/100. Accessibility: 61/100. Design: 85/100
- Interpretation: The weakest area is Accessibility, so improvements there should have the most visible effect on readiness.
- Recommended use: Use the score mix to choose the next workstream instead of treating every issue as equally urgent.

### LLM-readable file found

- Category: SEO / AEO
- Evidence: https://kern.cards/llms.txt returned HTTP 200.
- Interpretation: llms.txt can be a useful optional summary for agents, but it should not be treated as a guaranteed AI search ranking factor.
- Recommended use: Invest first in crawlability, helpful visible content, internal links, and accurate schema; add llms.txt as a tidy supplement.

### Rendered page experience snapshot

- Category: Design
- Evidence: Rendered text samples: 100. Contrast failures: 4. Console errors: 0. Horizontal overflow: 0px.
- Interpretation: The scan inspected the browser-rendered page, so contrast, runtime, layout, and timing signals are more representative than static markup alone.
- Recommended use: Use rendered checks to prioritize issues that visitors actually experience after JavaScript and CSS load.

### Rendered speed snapshot

- Category: Design
- Evidence: DOMContentLoaded: 339ms. Load complete: 399ms. First contentful paint: 452ms. Resources: 12. Scripts: 1. Images: 8. Third-party origins: 2. Transfer: not available.
- Interpretation: These are lightweight browser timings from one rendered scan, so they are useful directional signals rather than real-user performance proof.
- Recommended use: Use slow timings, high script counts, heavy transfer size, and many third-party origins to choose focused speed work, then verify important changes with analytics or field data when available.

### Rendered axe accessibility snapshot

- Category: Accessibility
- Evidence: axe violations: 2. Critical: 0. Serious: 1. Top rules: color-contrast, heading-order.
- Interpretation: axe-core catches common accessibility failures in the actual rendered DOM, but it is still automated coverage and not a full manual accessibility audit.
- Recommended use: Treat critical and serious axe failures as high-priority fixes, then manually review keyboard flow, focus states, screen reader meaning, and interaction states.

## Scope

FreeScan.app performs safe public checks only. It is not a penetration test, full SEO engagement, full accessibility audit, WCAG certification, backlink audit, rank tracker, or analytics platform.

Public reports expose the scanned public URL, safe scores, sanitized public evidence, and fix guidance. They do not include credentials, cookies, hidden form values, or sensitive response bodies.

Rescan same URL

Rerun the full deterministic scanner for kern.cards without re-entering the URL. The previous report stays saved so the next result can be compared against it.
