- Primary context: Improve structurecalculator.com at https://structurecalculator.com.
- Fix title: Add common public security headers.
- Scanner check: Common security headers.
- Category: Security.
- Status: fail.
- Severity: high.
- Priority: 5; lower numbers are more urgent.
- Score impact: 11 rule points lost.
- Evidence: Detected 2 of 5 common public security headers. Present: strict-transport-security, x-content-type-options. Missing: content-security-policy, 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.

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 (Strong).

Passed: 31. Failed: 7. Unknown: 0.
Strongest area: Accessibility. Weakest area: Design.

## Prioritized Fixes

### 1. Add common public security headers

- Category: Security
- Status: fail
- Severity: high
- Rule points lost: 11
- Evidence: Detected 2 of 5 common public security headers. Present: strict-transport-security, x-content-type-options. Missing: content-security-policy, 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. Publish a valid sitemap.xml

- Category: SEO / AEO
- Status: fail
- Severity: high
- Rule points lost: 12
- Evidence: HTTP 404 returned for sitemap_xml.
- Why it matters: A sitemap helps search engines discover the landing page and related public pages sooner.
- Fix: Add a static sitemap file or dynamic /sitemap.xml route with valid urlset or sitemapindex XML, include your public canonical URLs, and confirm it returns HTTP 200.

### 3. Fix rendered layout ergonomics

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 9
- Evidence: Horizontal overflow: 0px. Small tap targets: 18.
- 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.

### 4. Improve rendered speed signals

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 10
- Evidence: DOMContentLoaded: 361ms. Load complete: 881ms. First contentful paint: 544ms. Resources: 16. Scripts: 2. Images: 9. Third-party origins: 11. Transfer: not available.
- Why it matters: Slow pages lose impatient visitors and make every SEO, social, and paid-traffic visit work harder.
- Fix: Reduce render-blocking scripts/styles, compress and size images, defer non-critical JavaScript, reduce third-party tags, and keep above-the-fold content quick to paint.

### 5. Add trust signals

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 10
- Evidence: Detected 0 trust-signal keyword occurrence(s).
- Why it matters: Trust signals reduce hesitation when strangers see the product for the first time.
- Fix: Add honest proof such as customer quotes, usage stats, founder credibility, security notes, or relevant logos.

## Opportunities

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

- Impact: high
- Category: SEO / AEO
- Evidence: Pricing signals: 3. 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.

### Make trust and proof easier to detect

- Impact: medium
- Category: Design
- Evidence: Detected 0 trust-signal keyword occurrence(s).
- Why it matters: Visitors who arrive cold from search, social, or AI citations need proof before they submit a form, start a trial, or buy.
- Next step: Add honest proof such as customer quotes, recognizable logos, security notes, usage stats, reviews, case studies, or founder credibility.

### Add an optional LLM-readable site summary

- Impact: low
- Category: SEO / AEO
- Evidence: HTTP 404 returned for llms_txt.
- Why it matters: This is not required for Google AI features, but a concise public markdown summary can help AI agents and internal tools understand key pages.
- Next step: Publish a short llms.txt with product facts, audience, key public links, docs, pricing, support, and usage boundaries.

### 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.

### Speed up the rendered first impression

- Impact: medium
- Category: Design
- Evidence: DOMContentLoaded: 361ms. First contentful paint: 544ms. Scripts: 2. Third-party origins: 11. Transfer: not available.
- Why it matters: Visitors judge quality before reading much copy; a slow first render makes the product feel heavier and less trustworthy.
- Next step: Compress hero media, defer non-critical JavaScript, reduce third-party scripts, and keep the first viewport visually complete without waiting on heavy client work.

### Polish rendered responsive ergonomics

- Impact: medium
- Category: Design
- Evidence: Horizontal overflow: 0px. Small tap targets: 18.
- 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.

## Insights

### The page appears basically crawlable

- Category: SEO / AEO
- Evidence: HTTP 200. robots.txt: HTTP 200. sitemap.xml: not reachable. 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: 678. H1 count: 1. Audience signals: 5. CTA labels: Start with gravel.
- 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: StructureCalculator — Construction & DIY Material Calculators. H1: Construction and material calculations, supplier-ready.. Schema types: Organization.
- 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: 1. Types: Organization. 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: Design
- Evidence: SEO / AEO: 86/100. Security: 86/100. Accessibility: 100/100. Design: 67/100
- Interpretation: The weakest area is Design, 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 not found

- Category: SEO / AEO
- Evidence: HTTP 404 returned for llms_txt.
- 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: 0. 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: 361ms. Load complete: 881ms. First contentful paint: 544ms. Resources: 16. Scripts: 2. Images: 9. Third-party origins: 11. 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: 0. Critical: 0. Serious: 0. Top rules: none.
- 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.

## Role
Act as a focused expert website launch remediation agent for this workflow.
## Inputs
- Primary context: Improve structurecalculator.com at https://structurecalculator.com.
- Fix title: Make spacing more consistent.
- Scanner check: Spacing consistency.
- Category: Design.
- Status: fail.
- Severity: low.
- Priority: 25; lower numbers are more urgent.
- Score impact: 7 of 7 rule points lost.
- Evidence: Detected 0 spacing class/style signal(s).
- What needs attention: The page exposes few consistent spacing signals in class or inline styles.
- Why it matters: Consistent spacing helps the page feel deliberate and easier to scan.
- 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 consistent section padding, gaps, and margins across repeated content blocks.
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.

Rendered layout ergonomics

0/9

Horizontal overflow: 0px. Small tap targets: 18.

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.

## Launch Readiness

Close to ready (Strong).

Passed: 31. Failed: 7. Unknown: 0.
Strongest area: Accessibility. Weakest area: Design.

## Prioritized Fixes

### 1. Add common public security headers

- Category: Security
- Status: fail
- Severity: high
- Rule points lost: 11
- Evidence: Detected 2 of 5 common public security headers. Present: strict-transport-security, x-content-type-options. Missing: content-security-policy, 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. Publish a valid sitemap.xml

- Category: SEO / AEO
- Status: fail
- Severity: high
- Rule points lost: 12
- Evidence: HTTP 404 returned for sitemap_xml.
- Why it matters: A sitemap helps search engines discover the landing page and related public pages sooner.
- Fix: Add a static sitemap file or dynamic /sitemap.xml route with valid urlset or sitemapindex XML, include your public canonical URLs, and confirm it returns HTTP 200.

### 3. Fix rendered layout ergonomics

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 9
- Evidence: Horizontal overflow: 0px. Small tap targets: 18.
- 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.

### 4. Improve rendered speed signals

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 10
- Evidence: DOMContentLoaded: 361ms. Load complete: 881ms. First contentful paint: 544ms. Resources: 16. Scripts: 2. Images: 9. Third-party origins: 11. Transfer: not available.
- Why it matters: Slow pages lose impatient visitors and make every SEO, social, and paid-traffic visit work harder.
- Fix: Reduce render-blocking scripts/styles, compress and size images, defer non-critical JavaScript, reduce third-party tags, and keep above-the-fold content quick to paint.

### 5. Add trust signals

- Category: Design
- Status: fail
- Severity: medium
- Rule points lost: 10
- Evidence: Detected 0 trust-signal keyword occurrence(s).
- Why it matters: Trust signals reduce hesitation when strangers see the product for the first time.
- Fix: Add honest proof such as customer quotes, usage stats, founder credibility, security notes, or relevant logos.

## Opportunities

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

- Impact: high
- Category: SEO / AEO
- Evidence: Pricing signals: 3. 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.

### Make trust and proof easier to detect

- Impact: medium
- Category: Design
- Evidence: Detected 0 trust-signal keyword occurrence(s).
- Why it matters: Visitors who arrive cold from search, social, or AI citations need proof before they submit a form, start a trial, or buy.
- Next step: Add honest proof such as customer quotes, recognizable logos, security notes, usage stats, reviews, case studies, or founder credibility.

### Add an optional LLM-readable site summary

- Impact: low
- Category: SEO / AEO
- Evidence: HTTP 404 returned for llms_txt.
- Why it matters: This is not required for Google AI features, but a concise public markdown summary can help AI agents and internal tools understand key pages.
- Next step: Publish a short llms.txt with product facts, audience, key public links, docs, pricing, support, and usage boundaries.

### 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.

### Speed up the rendered first impression

- Impact: medium
- Category: Design
- Evidence: DOMContentLoaded: 361ms. First contentful paint: 544ms. Scripts: 2. Third-party origins: 11. Transfer: not available.
- Why it matters: Visitors judge quality before reading much copy; a slow first render makes the product feel heavier and less trustworthy.
- Next step: Compress hero media, defer non-critical JavaScript, reduce third-party scripts, and keep the first viewport visually complete without waiting on heavy client work.

### Polish rendered responsive ergonomics

- Impact: medium
- Category: Design
- Evidence: Horizontal overflow: 0px. Small tap targets: 18.
- 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.

## Insights

### The page appears basically crawlable

- Category: SEO / AEO
- Evidence: HTTP 200. robots.txt: HTTP 200. sitemap.xml: not reachable. 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: 678. H1 count: 1. Audience signals: 5. CTA labels: Start with gravel.
- 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: StructureCalculator — Construction & DIY Material Calculators. H1: Construction and material calculations, supplier-ready.. Schema types: Organization.
- 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: 1. Types: Organization. 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: Design
- Evidence: SEO / AEO: 86/100. Security: 86/100. Accessibility: 100/100. Design: 67/100
- Interpretation: The weakest area is Design, 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 not found

- Category: SEO / AEO
- Evidence: HTTP 404 returned for llms_txt.
- 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: 0. 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: 361ms. Load complete: 881ms. First contentful paint: 544ms. Resources: 16. Scripts: 2. Images: 9. Third-party origins: 11. 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: 0. Critical: 0. Serious: 0. Top rules: none.
- 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 structurecalculator.com without re-entering the URL. The previous report stays saved so the next result can be compared against it.
