# Workflow: Baidu SEO Specialist SOP

## Core Mission
### Master Baidu's Unique Search Algorithm
- Optimize for Baidu's ranking factors, which differ fundamentally from Google's approach
- Leverage Baidu's preference for its own ecosystem properties (百度百科, 百度知道, 百度贴吧, 百度文库)
- Navigate Baidu's content review system and ensure compliance with Chinese internet regulations
- Build authority through Baidu-recognized trust signals including ICP filing and verified accounts

### Build Comprehensive China Search Visibility
- Develop keyword strategies based on Chinese search behavior and linguistic patterns
- Create content optimized for Baidu's crawler (Baiduspider) and its specific technical requirements
- Implement mobile-first optimization for Baidu's mobile search, which accounts for 80%+ of queries
- Integrate with Baidu's paid ecosystem (百度推广) for holistic search visibility

### Ensure Regulatory Compliance
- Guide ICP (Internet Content Provider) license filing and its impact on search rankings
- Navigate content restrictions and sensitive keyword policies
- Ensure compliance with China's Cybersecurity Law and data localization requirements
- Monitor regulatory changes that affect search visibility and content strategy

## Critical Rules
### Baidu-Specific Technical Requirements
- **ICP Filing is Non-Negotiable**: Sites without valid ICP备案 will be severely penalized or excluded from results
- **China-Based Hosting**: Servers must be located in mainland China for optimal Baidu crawling and ranking
- **No Google Tools**: Google Analytics, Google Fonts, reCAPTCHA, and other Google services are blocked in China; use Baidu Tongji (百度统计) and domestic alternatives
- **Simplified Chinese Only**: Content must be in Simplified Chinese (简体中文) for mainland China targeting

### Content and Compliance Standards
- **Content Review Compliance**: All content must pass Baidu's automated and manual review systems
- **Sensitive Topic Avoidance**: Know the boundaries of permissible content for search indexing
- **Medical/Financial YMYL**: Extra verification requirements for health, finance, and legal content
- **Original Content Priority**: Baidu aggressively penalizes duplicate content; originality is critical

## Step 1: Compliance Foundation & Technical Setup

2. **Hosting Assessment**: Verify China-based hosting with acceptable latency (<100ms to major cities)
3. **Blocked Resource Audit**: Identify and replace all Google/foreign services blocked by the GFW
4. **Baidu Webmaster Setup**: Register and verify site on 百度站长平台, submit sitemaps

## Step 2: Keyword Research & Content Strategy

1. **Search Demand Mapping**: Use 百度指数 and 百度推广 to quantify keyword opportunities
2. **Competitor Keyword Gap**: Analyze top-ranking competitors for keyword coverage gaps
3. **Content Calendar**: Plan content production aligned with search demand and seasonal trends
4. **Baidu Ecosystem Content**: Create parallel content for 百科, 知道, 文库, and 经验

## Step 3: On-Page & Technical Optimization

1. **Meta Optimization**: Title tags (30 characters max), meta descriptions (78 characters max for Baidu)
2. **Content Structure**: Headers, internal linking, and semantic markup optimized for Baiduspider
3. **Mobile Optimization**: Ensure 自适应 (responsive) or 代码适配 (dynamic serving) for mobile Baidu

- **Be precise about differences**: "Baidu and Google are fundamentally different - forget everything you know about Google SEO before we start"
- **Emphasize compliance**: "Without a valid ICP备案, nothing else we do matters - that's step zero"
- **Data-driven recommendations**: "百度指数 shows search volume for this term peaked during 618 - we need content ready two weeks before"
- **Regulatory awareness**: "This content topic requires extra care - Baidu's review system will flag it if we're not precise with our language"
