## Usage

### Keyword Research

```python
def baidu_keyword_research(keyword):
    """Research keywords for Baidu SEO"""
    suggestions = []
    
    # Baidu Index (index.baidu.com equivalent)
    suggestions.append(get_baidu_index(keyword))
    
    # Baidu auto-suggest
    suggestions.append(get_baidu_suggest(keyword))
    
    # Competitor keywords
    competitors = get_top_ranking_pages(keyword, "baidu")
    for page in competitors[:5]:
        suggestions.extend(extract_keywords_from_page(page))
    
    return deduplicate(suggestions)
```

### Baidu-Specific Optimization

```python
def optimize_for_baidu(page_content):
    """Apply Baidu-specific optimizations"""
    checks = []
    
    # 1. ICP filing notice (required for .cn domains)
    if has_cn_domain():
        checks.append("⚠️ Add ICP备案号 in footer")
    
    # 2. Baidu Zhidao backlinks (Baidu's Q&A platform)
    checks.append("💡 Create Baidu Zhidao answers with link")
    
    # 3. Baidu Submit sitemap
    checks.append("✅ Submit to Baidu Webmaster Tools")
    
    # 4. Mobile optimization (critical for Baidu)
    if not is_mobile_friendly():
        checks.append("❌ Mobile optimization required for Baidu")
    
    # 5. Chinese lang tag
    if not has_zh_cn_tag():
        checks.append("❌ Add <html lang='zh-cmn-Hans'>")
    
    return checks
```

### Competitor Analysis

```python
def analyze_baidu_competitors(target_keyword):
    """Analyze why competitors rank on Baidu"""
    results = []
    pages = get_top_10_baidu_results(target_keyword)
    
    for page in pages:
        analysis = {
            "url": page.url,
            "title_length": len(page.title),  # Baidu: 28-30 chars optimal
            "meta_description": len(page.meta),  # Baidu: ~80 chars
            "has_https": page.url.startswith("https"),
            "has_schema": page.has_structured_data,
            "domain_age": get_domain_age(page.domain),
            "backlinks": estimate_backlinks(page.url),
            "content_length": estimate_word_count(page),
