# SEO & Discoverability Implementation Summary

## 📋 What Was Implemented

### Core Feature: SEO & Discoverability Scoring (15% weight)

A comprehensive SEO scoring system that evaluates product listings for search engine optimization and customer discoverability across 4 key dimensions:

| Dimension | Weight | What It Checks |
|-----------|--------|----------------|
| **Keyword Coverage** | 35% | Are mandatory attributes mentioned in title/description? |
| **Semantic Richness** | 30% | Description quality, vocabulary diversity, descriptive language |
| **Backend Keywords** | 20% | Presence of high-value search terms and category keywords |
| **Title Optimization** | 15% | Title length (50-100 chars), structure, no keyword stuffing |

## 🎯 Why This Approach?

### Technology Stack Chosen

| Technology | Purpose | Why This Choice |
|------------|---------|-----------------|
| **KeyBERT** | Keyword extraction | Fast, accurate, open-source. Best for e-commerce SEO |
| **Sentence-Transformers** | Semantic similarity | Lightweight, pre-trained models. Better than full LLMs |
| **Google Gemini** | AI suggestions | Already in your stack. Provides context-aware recommendations |
| **spaCy** | NLP preprocessing | Fast entity recognition, existing in your code |
| **RapidFuzz** | Fuzzy matching | Existing dependency, handles typos well |

### Alternatives Considered & Rejected

❌ **OpenAI GPT** - Too expensive ($0.02/1k tokens), slower, overkill for this use case  
❌ **SEMrush/Ahrefs** - $100-500/month, external API, limited customization  
❌ **LLaMA 2** - Requires GPU, complex setup, slower inference  
❌ **Full BERT models** - Too heavy, KeyBERT uses lighter sentence transformers

├── Content Rules Compliance (15%) ← NEW

└── Description Quality (15%)
```

## API Endpoints

### Score Product (with content rules)
```http
POST /api/score/
Content-Type: application/json

{
  "product": {
    "sku": "PROD-001",
    "category": "Electronics",
    "title": "Product Title",
    "description": "Product description...",
    "seo_title": "SEO Title",
    "seo_description": "SEO Description...",
    "attributes": { }
  }
}
```

### Get Content Rules
```http
GET /api/content-rules/
GET /api/content-rules/?category=Electronics
```

### Create Content Rule
```http
POST /api/content-rules/
Content-Type: application/json

{
  "category": "Electronics",
  "field_name": "title",
  "min_word_count": 5,
  "must_contain_keywords": ["brand", "model"]
}
```

## Common Validation Patterns

### Pattern 1: Minimum Content Length
```python
{
    'field_name': 'description',
    'min_word_count': 50,
    'is_mandatory': True
}
```

### Pattern 2: SEO Character Limits
```python
{
    'field_name': 'seo_title',
    'min_length': 40,
    'max_length': 60
}
```

### Pattern 3: Required Keywords
```python
{
    'field_name': 'title',
    'must_contain_keywords': ['Apple', 'Samsung', 'Sony']
}
```

### Pattern 4: Global + Category Override
```python
# Global rule
{'category': None, 'field_name': 'title', 'min_word_count': 10}

# Category override
{'category': 'Electronics', 'field_name': 'title', 'min_word_count': 5}

# Result: Electronics uses 5, others use 10
```

## Python Usage

### Create Rule
```python
from core.models import ProductContentRule

ProductContentRule.objects.create(
    category='Electronics',
    field_name='description',
    is_mandatory=True,
    min_word_count=100,
    must_contain_keywords=['warranty', 'specifications']
)
```

### Score with Rules
```python
from core.services.attribute_scorer import AttributeQualityScorer
from core.models import CategoryAttributeRule, ProductContentRule

scorer = AttributeQualityScorer()

# Get rules
attr_rules = list(CategoryAttributeRule.objects.filter(category='Electronics').values())
content_rules = list(ProductContentRule.objects.filter(
    models.Q(category__isnull=True) | models.Q(category='Electronics')
).values())

# Score
result = scorer.score_product(
    product_data,
    attr_rules,
    content_rules=content_rules
)

print(f"Score: {result['final_score']}/100")
print(f"Content Compliance: {result['breakdown']['content_rules_compliance']}")
```

### Query Rules
```python
# All rules
ProductContentRule.objects.all()

# Global rules only
ProductContentRule.objects.filter(category__isnull=True)

# Category-specific
ProductContentRule.objects.filter(category='Electronics')

# By field
ProductContentRule.objects.filter(field_name='title')

# Mandatory rules
ProductContentRule.objects.filter(is_mandatory=True)
```

## Issue Types Generated

Content rules generate specific issues:

| Issue Type | Example |
|------------|---------|
| Missing Mandatory | `"SEO Title: Required field is missing"` |
| Too Short | `"Description: Too short (20 words, minimum 50)"` |
| Too Long | `"Title: Too long (150 chars, maximum 100)"` |
| Missing Keywords | `"Title: Must contain at least one of: Apple, Samsung"` |
| Regex Mismatch | `"Email: Format does not match required pattern"` |

## Validation Flow

```
1. Fetch Rules
   ├── Global rules (category=NULL)
   └── Category rules

2. Merge Rules
   └── Category rules override global

3. For Each Field:
   ├── Check mandatory
   ├── Check length (chars)
   ├── Check word count
   ├── Check keywords
   └── Check regex

4. Calculate Scores
   ├── Per-field score
   └── Weighted average

5. Return Results
   ├── overall_content_score
   ├── field_scores
   ├── issues
   └── suggestions
```

## Sample Rules Provided

### Global Rules (All Categories)
- `description`: 200-500 words (mandatory)
- `title`: 40-100 words (mandatory)
- `seo_title`: 40-60 characters (mandatory)
- `seo_description`: 120-160 characters (mandatory)

### Electronics Category
- `title`: Min 4 words, must contain brand (Apple/Samsung/Sony/HP)

### Clothing Category
- `title`: Must contain product type (T-Shirt/Hoodie/Jacket)

## Testing

### Unit Test
```python
from core.services.content_rules_scorer import ContentRulesScorer

scorer = ContentRulesScorer()
result = scorer.score_content_fields(product, rules)

assert result['overall_content_score'] > 80
assert len(result['issues']) == 0
```

### Integration Test
```bash
python test_content_rules_integration.py
```

### API Test
```bash
curl -X POST http://localhost:8000/api/score/ \
  -H "Content-Type: application/json" \
  -d @sample_product.json
```

## Troubleshooting Checklist

- [ ] Migrations run? `python manage.py migrate`
- [ ] Sample data loaded? `python manage.py load_sample_content_rules`
- [ ] Rules exist? `ProductContentRule.objects.count()`
- [ ] Product has content fields? Check `title`, `description`, etc.
- [ ] Category name matches? Case-sensitive
- [ ] Cache cleared? `cache.delete(f"content_rules_{category}")`
- [ ] Check logs? Look for `[Content Rules]` messages

## Performance Tips

✅ **Do:**
- Cache rules per category (1 hour TTL)
- Fetch rules once for batch processing
- Use database indexes (already configured)
- Clear cache after rule updates

❌ **Don't:**
- Fetch rules for each product in a loop
- Create overly complex regex patterns
- Set extreme constraints (min=1000 words)
- Forget to invalidate cache

## Migration Checklist

Migrating from old validation code:

- [ ] Identify existing validation logic
- [ ] Create equivalent `ProductContentRule` entries
- [ ] Test with sample products
- [ ] Remove old validation code
- [ ] Update documentation
- [ ] Train team on new system
- [ ] Monitor scores after deployment

## Support & Documentation

- **Full Guide**: `CONTENT_RULES_INTEGRATION.md`
- **Model Definition**: `models.py` (line ~50)
- **Scorer Logic**: `content_rules_scorer.py`
- **Sample Data**: `sample_data.py` (SAMPLE_CONTENT_RULES)
- **API Docs**: `urls.py` + `views.py`

**Quick Help:**
```bash
# Show all rules
python manage.py shell -c "from core.models import ProductContentRule; print(ProductContentRule.objects.all())"

# Count by category
python manage.py shell -c "from core.models import ProductContentRule; from django.db.models import Count; print(ProductContentRule.objects.values('category').annotate(count=Count('id')))"

# Delete all rules
python manage.py shell -c "from core.models import ProductContentRule; ProductContentRule.objects.all().delete()"
```
