GEO Audit Orchestration Skill

Purpose

This skill performs a comprehensive Generative Engine Optimization (GEO) audit of any website. GEO is the practice of optimizing web content so that AI systems (ChatGPT, Claude, Perplexity, Gemini, etc.) can discover, understand, cite, and recommend it. This audit measures how well a site performs across all GEO dimensions and produces an actionable improvement plan.

Key Insight

Traditional SEO optimizes for search engine rankings. GEO optimizes for AI citation and recommendation. Sites that score high on GEO metrics see 30-115% more visibility in AI-generated responses (Georgia Tech / Princeton / IIT Delhi 2024 study). The two disciplines overlap but have distinct requirements.

Audit Workflow

Phase 1: Discovery and Reconnaissance

Step 1: Fetch Homepage and Detect Business Type

1. Use WebFetch to retrieve the homepage at the provided URL.
2. Extract the following signals:

- Page title, meta description, H1 heading - Navigation menu items (reveals site structure) - Footer content (reveals business info, location, legal pages) - Schema.org markup on homepage (Organization, LocalBusiness, etc.) - Pricing page link (SaaS indicator) - Product listing patterns (E-commerce indicator) - Blog/resource section (Publisher indicator) - Service pages (Agency indicator) - Address/phone/Google Maps embed (Local business indicator)

1. Classify the business type using these patterns:

Step 2: Crawl Sitemap and Internal Links

1. Attempt to fetch /sitemap.xml and /sitemap_index.xml.
2. If sitemap exists, extract up to 50 unique page URLs prioritized by:

- Homepage (always include) - Top-level navigation pages - High-value pages (pricing, about, contact, key service/product pages) - Blog posts (sample 5-10 most recent) - Category/landing pages

1. If no sitemap exists, crawl internal links from the homepage:

- Extract all <a href> links pointing to the same domain - Follow up to 2 levels deep - Prioritize pages linked from main navigation

1. Respect robots.txt directives -- do not fetch disallowed paths.
2. Enforce a maximum of 50 pages and a 30-second timeout per fetch.

Step 3: Collect Page-Level Data

For each page in the crawl set, record:

• URL, title, meta description, canonical URL
• H1-H6 heading structure
• Word count of main content
• Schema.org types present
• Internal/external link counts
• Images with/without alt text
• Open Graph and Twitter Card meta tags
• Response status code
• Whether the page has structured data

Phase 2: Parallel Subagent Delegation

Delegate analysis to 5 specialized subagents. Each subagent operates on the collected page data and produces a category score (0-100) plus findings.

Subagent 1: AI Visibility Analysis (geo-ai-visibility)

• Analyze content blocks for quotability by AI systems (citability scoring)
• Check AI crawler access via robots.txt and llms.txt presence
• Scan brand presence across YouTube, Reddit, Wikipedia, LinkedIn
• Score brand authority signals that AI models use for entity recognition

Subagent 2: Platform Optimization (geo-platform-analysis)

• Assess readiness for Google AI Overviews, ChatGPT, Perplexity, Gemini, Bing Copilot
• Check platform-specific ranking factors and optimization opportunities

Subagent 3: Technical GEO Infrastructure (geo-technical)

• Analyze robots.txt for AI crawler access
• Verify meta tags, headers, and technical accessibility for AI systems
• Check page speed, server-side rendering, and Core Web Vitals
• Assess security headers and mobile optimization

Subagent 4: Content E-E-A-T Quality (geo-content)

• Evaluate Experience, Expertise, Authoritativeness, Trustworthiness signals
• Check author bios, credentials, source citations
• Assess content freshness, depth, and originality
• Verify "About" page quality and team credentials

Subagent 5: Schema & Structured Data (geo-schema)

• Validate all schema.org markup
• Check for GEO-critical schema types (FAQ, HowTo, Organization, Product, Article)
• Assess schema completeness and accuracy
• Identify missing schema opportunities

Phase 3: Score Aggregation and Report Generation

Composite GEO Score Calculation

The overall GEO Score (0-100) is a weighted average of six category scores:

Formula:

GEO_Score = (Citability * 0.25) + (Brand * 0.20) + (EEAT * 0.20) + (Technical * 0.15) + (Schema * 0.10) + (Platform * 0.10)

Score Interpretation

Issue Severity Classification

Every issue found during the audit is classified by severity:

Critical (Fix Immediately)

• All AI crawlers blocked in robots.txt
• No indexable content (JavaScript-rendered only with no SSR)
• Domain-level noindex directive
• Site returns 5xx errors on key pages
• Complete absence of any structured data
• Brand not recognized as an entity by any AI system

High (Fix Within 1 Week)

• Key AI crawlers (GPTBot, ClaudeBot, PerplexityBot) blocked
• No llms.txt file present
• Zero question-answering content blocks on key pages
• Missing Organization or LocalBusiness schema
• No author attribution on content pages
• All content behind login/paywall with no preview

Medium (Fix Within 1 Month)

• Partial AI crawler blocking (some allowed, some blocked)
• llms.txt exists but is incomplete or malformed
• Content blocks average under 50 citability score
• Missing FAQ schema on pages with FAQ content
• Thin author bios without credentials
• No Wikipedia or Reddit brand presence

Low (Optimize When Possible)

• Minor schema validation errors
• Some images missing alt text
• Content freshness issues on non-critical pages
• Missing Open Graph tags
• Suboptimal heading hierarchy on some pages
• LinkedIn company page exists but is incomplete

Quality Gates

• Page Limit: Never crawl more than 50 pages per audit. Prioritize high-value pages.
• Timeout: 30-second maximum per page fetch. Skip pages that exceed this.
• Robots.txt: Always check and respect robots.txt before crawling. Note any AI-specific directives.
• Rate Limiting: Wait at least 1 second between page fetches to avoid overloading the server.
• Error Handling: Log failed fetches but continue the audit. Report fetch failures in the appendix.
• Content Type: Only analyze HTML pages. Skip PDFs, images, and other binary content.
• Deduplication: Canonicalize URLs before crawling. Skip duplicate content (e.g., HTTP vs HTTPS, www vs non-www, trailing slashes).
