## 🎯 Knowledge Sharing

### Documentation Standards
**Code Documentation**:
```python
def analyze_seo_performance(url: str, keywords: List[str]) -> SEOAnalysis:
    """
    Analyze SEO performance for a given URL.
    
    Args:
        url: The URL to analyze
        keywords: List of target keywords
        
    Returns:
        SEOAnalysis object with analysis results
        
    Raises:
        ValidationError: If URL is invalid
        AnalysisError: If analysis fails
    """
    # Implementation here
```

**API Documentation**:
```python
@app.get("/api/seo/analyze", response_model=SEOAnalysisResponse)
async def analyze_seo(
    url: str = Query(..., description="URL to analyze"),
    keywords: List[str] = Query(..., description="Target keywords")
) -> SEOAnalysisResponse:
    """
    Analyze SEO performance for a URL.
    
    This endpoint performs comprehensive SEO analysis including:
    - Technical SEO audit
    - Content analysis
    - Performance metrics
    - Keyword optimization
    
    Returns detailed analysis results and recommendations.
    """
```
