How the audit runs

Six sequential steps from URL to report

01

Parallel data fetch

Fetches six sources simultaneously: page content, schema and meta tags, robots.txt, sitemap.xml, llms.txt, and server response time via curl. No sequential waiting — all sources load at once.

02

48-check grading

Grades every check with one of four verdicts: Pass (score 1.0), Warning (0.5), Fail (0.0), or Manual (excluded from scoring). Each verdict includes an evidence note of one sentence.

03

Score calculation

Per-category score = sum of check scores / scoreable checks × 100. Overall score = sum across all 48 checks / total scoreable. Manual checks are excluded from both numerator and denominator.

04

Top-fixes prioritization

Ranks all Fail and Warning checks by impact tier: High (known LLM citation levers), Medium (content quality and trust signals), Low (polish and freshness). Lists the top 10 fixes in priority order.

05

HTML report generation

Reads the report template, populates the AUDIT_DATA object with every real value from this audit, and writes a standalone HTML file — open in any browser, no server needed.

What the Landing Page Auditor actually is?

A 48-check GEO and AI discoverability audit, not a basic SEO checker

The landing-page-auditor skill fetches any landing or service page URL and audits it across 48 checks in 10 categories. It runs all six data fetches in parallel — page content, schema, robots.txt, sitemap, llms.txt, and TTFB — then grades every check and calculates a 0-100 overall score.

The categories go beyond traditional SEO: Category 6 (Semantic Answer Coverage) tests whether the page answers What, Who, How, Why, and How Much — the five questions AI systems look for when deciding whether to cite a page. Category 8 (Content Richness & Multimodal) checks whether the page is listed in llms.txt, a 2025 signal that directly affects AI crawler access.

The output is a standalone HTML file saved to disk with the domain in the filename. It shows per-category scores with color-coded thresholds (green 80-100, amber 60-79, red 0-59), individual check verdicts with evidence notes, and a ranked top-10 fix list with impact tiers. No login, no dashboard — open in any browser.

When it Triggers?

Triggers on any URL provided with intent to audit: 'audit this page', 'score this URL', 'check GEO for', 'is this page AI-ready', 'run a GEO audit', 'LLM page check', 'how would AI read this page', 'landing page score', 'AI discoverability check', or 'can AI cite this page'.

Pass a URL as the argument and the skill proceeds directly. If no URL is provided, it asks for one before starting. Normalizes the URL before fetching: adds https://, strips trailing slashes, preserves the full path, and extracts the domain root for auxiliary file checks.

How the scoring works

Four verdicts, two score levels, one priority framework

Pass (1.0): Clearly present and meets the criteria. Contributes full weight to the category and overall score.

Warning (0.5): Partially present, improvable, or ambiguous. Half-weight contribution — shows the signal exists but isn't fully optimized.

Fail (0.0): Missing, broken, or clearly absent. Zero contribution. Appears in the top-fixes list.

Manual (○): Requires human review. Excluded from both numerator and denominator so it doesn't penalize the score unfairly. Used for checks like 'outdated stats or claims removed' that can't be verified programmatically.

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

48 checks across 10 categories: Content Clarity (5), Structure & Scannability (5), Entity & Fact Signal (5), Trust & Authority (4), FAQ & Schema Signals (5), Semantic Answer Coverage (5), Internal Linking (5), Content Richness (3), Freshness & Maintenance (4), and Crawlability & Technical (7). One of the 4 freshness checks is Manual.
Each check scores 1.0 (Pass), 0.5 (Warning), or 0.0 (Fail). Manual checks are excluded. Per-category score = sum of check scores / scoreable checks × 100. Overall = sum across all categories / total scoreable checks × 100. Score bands: green 80-100, amber 60-79, red 0-59.
A check that requires human review to verify accurately — like whether outdated stats have been removed. Manual checks get an ○ symbol, excluded from both numerator and denominator so they don't penalize the score. The audit notes each one clearly and tells you what to review.
Six sources in parallel: (1) page content — headings, paragraphs, lists, links, dates; (2) page schema — JSON-LD blocks, all images with alt text, meta title, canonical, robots tag; (3) robots.txt — AI crawler directives; (4) sitemap.xml — page entry and lastmod; (5) llms.txt — whether the page path is listed; (6) server TTFB via curl.
A standalone dark-theme HTML file with the domain in the filename (e.g. infrasity-com-landing-page-audit.html). Shows overall score with color-coded badge, per-category score cards, individual check rows with Pass/Warning/Fail/Manual status and evidence notes, and a ranked top-10 fix list with impact tiers.
Any publicly accessible URL. If the page is entirely JS-rendered (raw HTML under 100 words), it notes the limitation and grades what it can. If robots.txt or sitemap.xml returns 404, it marks those checks accordingly and continues. Authentication-gated pages cannot be audited.
