## OVERVIEW

### Objectives
- ✅ Support product content generation
- ✅ Support service page generation
- ✅ Support taxonomy generation
- ✅ Extend linker for all content types
- ✅ Extend optimizer for all content types

### Key Principles
- **Unified Model**: All content types use same Content model
- **Type-Specific Prompts**: Different prompts per content type
- **Universal Processing**: Linker and Optimizer work on all types

## CONTENT MODEL EXTENSIONS

### 8.1 Content Model Extensions

| Task | File | Dependencies | Implementation |
|------|------|--------------|----------------|
| **Add entity_type field** | `business/content/models.py` | Phase 1 | Content type field |
| **Add json_blocks field** | `business/content/models.py` | Phase 1 | Structured content blocks |
| **Add structure_data field** | `business/content/models.py` | Phase 1 | Content structure data |

**Content Model Extensions**:
```python
# business/content/models.py
class Content(SiteSectorBaseModel):
    # Existing fields...
    
    # NEW: Entity type
    entity_type = models.CharField(
        max_length=50,
        choices=[
            ('blog_post', 'Blog Post'),
            ('article', 'Article'),
            ('product', 'Product'),
            ('service', 'Service Page'),
            ('taxonomy', 'Taxonomy Page'),
            ('page', 'Page'),
        ],
        default='blog_post'
    )
    
    # NEW: Structured content
    json_blocks = models.JSONField(default=list)
    structure_data = models.JSONField(default=dict)
```
