- How to {keyword}
- Why {keyword}
- When to {keyword}
- Where to {keyword}

### Comparative Modifiers

## Clustering Algorithm

1. **Extract Seed Topics**: Identify main themes from expanded list
2. **Group by Semantic Similarity**: Keywords with overlapping meaning
3. **Map Intent**: Assign I/C/T/N to each cluster
4. **Identify Pillar**: Highest-volume, broadest term = pillar
5. **Map Supporting**: Lower-volume terms support pillar

## Cluster Structure

```
PILLAR: "content marketing" (highest volume)
+-- CLUSTER: "content marketing strategy" (commercial)
|   +-- content marketing plan template
|   +-- content marketing framework
|   +-- how to create content marketing strategy
+-- CLUSTER: "content marketing examples" (informational)
|   +-- B2B content marketing examples
|   +-- content marketing case studies
|   +-- content marketing success stories
+-- CLUSTER: "content marketing tools" (commercial)
    +-- best content marketing tools
    +-- content marketing software
    +-- content marketing platforms
```

## Intent Classification Rules

| Signal | Intent |
|--------|--------|
| "what is", "how to", "guide" | Informational |
| "best", "vs", "review", "compare" | Commercial |
| "buy", "price", "discount", brand | Transactional |
| Brand name, specific product | Navigational |

## Output Format

When generating keyword clusters, use this format:

```markdown
## Keyword Cluster Report

**Seed Keyword**: {seed}

**Clusters**: {cluster_count}

### Cluster 1: {cluster_name}
**Intent**: {intent}
**Funnel Stage**: {stage}
**Keywords**:
1. {keyword1} - {estimated_volume}
2. {keyword2} - {estimated_volume}
...

### Cluster 2: {cluster_name}
