What It Does

GEO Analyzer examines content for the signals AI systems use when selecting sources to cite:

• Claim Density - Extractable facts per 100 words
• Information Density - Word count vs predicted AI coverage
• Answer Frontloading - How quickly key information appears
• Semantic Triples - Structured (subject, predicate, object) relationships
• Entity Recognition - Named entities AI can reference
• Sentence Structure - Optimal length for AI parsing

The analysis runs locally using Claude Sonnet 4.5 for semantic extraction. No external services, no data leaving your machine.

Installation

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "geo-analyzer": {
      "command": "npx",
      "args": ["-y", "@houtini/geo-analyzer@latest"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Config locations:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Restart Claude Desktop after saving.

Claude Code (CLI)

Claude Code uses a different registration mechanism -- it doesn't read claude_desktop_config.json. Use claude mcp add instead:

claude mcp add -e ANTHROPIC_API_KEY=sk-ant-... -s user geo-analyzer -- npx -y @houtini/geo-analyzer@latest

Verify with:

claude mcp get geo-analyzer

You should see Status: Connected.

Requirements

• Node.js 20+
• Anthropic API key (console.anthropic.com)

Usage Examples

Analyse a Published URL

Analyse https://example.com/article for "topic keywords"

The topic context helps score relevance but isn't required:

Analyse https://example.com/article

Analyse Text Directly

Paste content for analysis (minimum 500 characters):

Analyse this content for "sim racing wheels":

[Your content here]

Summary Mode

Get condensed output without detailed recommendations:

Analyse https://example.com/article with output_format=summary

Output

Scores (0-10)

Key Metrics

Information Density:

• Word count with coverage prediction
• Optimal range: 800-1,500 words
• Pages under 1K words: ~61% AI coverage
• Pages over 3K words: ~13% AI coverage

Answer Frontloading:

• Claims and entities in first 100/300 words
• First claim position
• Score indicating answer immediacy

Claim Density:

• Target: 4+ claims per 100 words
• Extractable facts, statistics, measurements

Sentence Length:

• Target: 15-20 words average
• Matches Google's ~15.5 word chunk extraction

Recommendations

Prioritised suggestions with:

• Specific locations in content
• Before/after examples
• Rationale based on research

Tools

analyze_url

Fetches and analyses published web pages.

analyze_text

Analyses pasted content directly.

Troubleshooting

"ANTHROPIC_API_KEY is required" Add your API key to the env section in config.

"Cannot find module" after config change Restart Claude Desktop completely.

"Content too short" Minimum 500 characters required for meaningful analysis.

Paywalled content returns errors The analyser can only access publicly available pages.

Performance

• URL analysis: ~8-10 seconds
• Text analysis: ~5-7 seconds
• Cost: ~$0.14 per analysis (Sonnet 4.5)

Migration from v1.x

v2.0 removed external dependencies. Update your config:

Old (v1.x):

{
  "env": {
    "GEO_WORKER_URL": "https://...",
    "JINA_API_KEY": "jina_..."
  }
}

New (v2.x):

{
  "env": {
    "ANTHROPIC_API_KEY": "sk-ant-..."
  }
}

Development

git clone https://github.com/houtini-ai/geo-analyzer.git
cd geo-analyzer
npm install
npm run build

Research Foundation

The analysis methodology draws from peer-reviewed research and empirical studies:

MIT GEO Paper (2024)

Aggarwal et al., "GEO: Generative Engine Optimization" - ACM SIGKDD

Key findings applied:

• Claim density target of 4+ per 100 words
• Optimal sentence length of 15-20 words
• 40% improvement in AI citation rates with extractability focus

arxiv.org/abs/2311.09735

Dejan AI Grounding Research (2025)

Empirical analysis of 7,060 queries and 2,275 pages

Key findings applied:

• ~2,000 word total grounding budget per query
• Rank #1 source gets 531 words (28% of budget)
• Rank #5 source gets 266 words (13% of budget)
• Average extraction chunk: 15.5 words
• Pages <1K words: 61% coverage
• Pages 3K+ words: 13% coverage
