GEO Analyzer


Content analysis for AI search visibility. Measures what actually matters for getting cited by ChatGPT, Claude, Perplexity, and Google AI Overviews.

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.

Usage Examples

$3

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

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

`
Analyse https://example.com/article
`

$3

Paste content for analysis (minimum 500 characters):

`
Analyse this content for "sim racing wheels":

[Your content here]
`

$3

Get condensed output without detailed recommendations:

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

Output

- First claim position
- Score indicating answer immediacy

Claim Density:
- Target: 4+ claims per 100 words
- Extractable facts, statistics, measurements

Sentence Length:

- Rationale based on research

Tools

$3

Fetches and analyses published web pages.

| Parameter | Required | Description |
|-----------|----------|-------------|
| url | Yes | URL to analyse |
| query | No | Topic context for relevance scoring |
| output_format | No | detailed (default) or summary |

$3

Analyses pasted content directly.

| Parameter | Required | Description |
|-----------|----------|-------------|
| content | Yes | Text to analyse (min 500 chars) |
| query | No | Topic context for relevance scoring |
| output_format | No | detailed (default) or summary |

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

New (v2.x):
`json
{
"env": {
"ANTHROPIC_API_KEY": "sk-ant-..."
}
}
`

Development

`bash
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:

$3

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

$3

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
