Landing Page Auditor

Landing Page GEO & LLM Auditor

Audits any landing or service page across 48 checks in 10 categories. Given a URL, fetch all required data, grade every check, calculate scores per category and overall, then render a standalone HTML report.

Step 0 — Parse and Confirm the URL

If the user provided a URL in the invocation arguments, use it directly. If not, ask:

"Please provide the URL of the page you'd like to audit."

Normalisation rules:

• Ensure the URL starts with https://
• Strip trailing slashes
• Keep the full path (e.g. https://infrasity.com/claude-skills, not just infrasity.com)
• Extract the bare domain for file naming (e.g. infrasity.com)
• Extract the domain root for auxiliary files (strip subdomains only if they differ — check both)

Echo back the resolved URL before proceeding:

"Auditing {URL} — fetching data now..."

Step 1 — Fetch All Required Data in Parallel

Run ALL of the following fetches simultaneously. Do not wait for one to complete before starting the next.

1a — Page Content Overview (WebFetch pass 1)

Fetch {URL} with this prompt:

"Return the complete text content of the page. Include: all headings (H1, H2, H3, H4) with their exact levels and text, all paragraph text, all list items, the opening sentence and first 150 words of body text (excluding nav), any FAQ section content, testimonial or social proof text, pricing info, stats and numbers, target audience language, comparison language like 'unlike X' or 'instead of', negative scoping like 'not for X', measurable outcome claims like 'reduced X by Y%', all internal links with href and anchor text, all external links with href and anchor text, any visible date or 'last updated' text, any breadcrumb navigation, and any comparison tables."

1b — Page Schema and Technical (WebFetch pass 2)

Fetch {URL} with this prompt:

"Return: 1) All JSON-LD schema blocks verbatim including their @type values, 2) All image tags with exact src and alt attributes — list every image, 3) The meta title tag content, 4) The meta description content, 5) The canonical URL from the canonical link tag, 6) The robots meta tag content, 7) Any BreadcrumbList schema, 8) Any Service, ProfessionalService, SoftwareApplication or Product schema, 9) Any FAQPage schema, 10) Whether page content is visible in raw HTML without JavaScript execution."

1c — robots.txt (WebFetch)

Fetch {ROOT_DOMAIN}/robots.txt with this prompt:

"Return the complete robots.txt content. List every User-agent entry and its Allow/Disallow rules. Specifically call out rules for: GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, and any wildcard User-agent. Note the Sitemap directive URL if present."

1d — sitemap.xml (WebFetch)

Fetch {ROOT_DOMAIN}/sitemap.xml with this prompt:

"Check if {FULL_URL} or any variant appears in this sitemap. Return the exact URL match, its lastmod date, changefreq, and priority. Also return the total number of URLs in the sitemap."

If the first sitemap is an index file referencing sub-sitemaps, fetch the most relevant sub-sitemap and repeat the check.

1e — llms.txt (WebFetch)

Fetch {ROOT_DOMAIN}/llms.txt with this prompt:

"Return the full content of this llms.txt file. List every URL or path mentioned. Specifically check whether '{PAGE_PATH}' (the path portion of the target URL) or the full URL '{FULL_URL}' appears anywhere in the file."

1f — Server Response Time (Bash / curl)

RESPONSE_MS=$(curl -o /dev/null -s -w "%{time_starttransfer}" --max-time 15 "{URL}" | awk '{printf "%.0f", $1 * 1000}')
echo "TTFB: ${RESPONSE_MS}ms"

If curl is unavailable, mark check 10.3 as ⚠ Warning with note "Response time could not be measured."

Step 2 — Grade All 48 Checks

Use the fetched data to evaluate every check below. Assign one of four verdicts:

Also write a short evidence note for each check (1 sentence max) — what you found or didn't find.

Category 1 — Content Clarity & Directness (5 checks)

1.1 — Clear opening sentence describing the service

Look at the first sentence of body text (exclude navigation, hero buttons, GitHub badges).

• Pass: First sentence clearly states what the product/service is or does
• Warn: Opening exists but is preceded by several non-sentence elements (buttons, badges, CTAs) that push it past the visual fold

1.2 — Service definition in first 100 words ('X is a [type] that…')

Count the first 100 words of actual body copy (strip nav links, CTA button text, icon labels).

• Fail: Fewer than 100 words in raw HTML; page is client-side rendered and largely invisible to AI crawlers

Step 3 — Calculate Scores

Per-category score (out of 100)

Category Score = (Σ check_scores) / (total_scoreable_checks_in_category) × 100

Where:
  check_score = 1.0 for Pass
  check_score = 0.5 for Warning
  check_score = 0.0 for Fail
  Manual checks are excluded from both numerator and denominator

Round to the nearest integer.

Overall score (out of 100)

Overall Score = (Σ all_check_scores across all categories) / (total_scoreable_checks) × 100

Total checks: 48. Manual checks excluded from denominator.

Score colour thresholds

Step 4 — Determine Top Fixes

After grading, compile a ranked list of all Fail and Warning checks sorted by impact. Use this priority framework:

Impact tier assignment:

List the top 10 fixes in priority order. For each fix, include:

• Priority number (P1–P10)
• Impact tier (High / Medium / Low)
• Category name
• Fix title (what to add or change)
• Detail note (one sentence explaining why it matters or what to do)

Step 5 — Generate the HTML Report

Read references/html-template.md for the complete HTML structure.

Populate the AUDIT_DATA JavaScript object in the template with all real data from this audit:

const AUDIT_DATA = {
  url: "{FULL_URL}",
  domain: "{BARE_DOMAIN}",
  date: "{AUDIT_DATE}",          // e.g. "June 16, 2026"
  overallScore: {OVERALL_SCORE},
  totalChecks: 48,
  scoreable: {SCOREABLE_COUNT},  // 48 minus manual count
  pass: {PASS_COUNT},
  warn: {WARN_COUNT},
  fail: {FAIL_COUNT},
  manual: {MANUAL_COUNT},
  categories: [
    {
      name: "Content Clarity & Directness",
      score: {CAT1_SCORE},
      pass: {CAT1_PASS},
      warn: {CAT1_WARN},
      fail: {CAT1_FAIL},
      manual: 0,
      checks: [
        { status: "pass|warn|fail|manual", label: "Clear opening sentence", note: "Evidence note — one sentence" },
        // ... all 5 checks
      ]
    },
    // ... all 10 categories in order
  ],
  topFixes: [
    { priority: 1, impact: "High", category: "Category Name", fix: "Fix title", detail: "One sentence detail" },
    // ... up to 10 fixes
  ]
};

Do not leave any placeholder values unfilled. Every number must be a real value from this audit.

Step 6 — Write and Present

Write the completed HTML report to a file in the current working directory:

{domain}-landing-page-audit.html

For example: infrasity-com-landing-page-audit.html

After writing, tell the user:

"Audit complete. Report saved to {filename}.html — open it in any browser. Overall score: {SCORE}/100 ({PASS} pass · {WARN} warn · {FAIL} fail · {MANUAL} manual) Top fix: {P1_FIX}"

Then offer to explain any category in detail or generate a prioritised action plan.
