## 1. Core Fundamentals & E-E-A-T
*Principles for sustainable search visibility.*

### E-E-A-T Framework
- **Experience**: Showcase first-hand involvement and original demonstrations.
- **Expertise**: Verify subject-matter competence and accuracy.
- **Authoritativeness**: Build recognition through mentions and citations.
- **Trustworthiness**: Ensure transparency, HTTPS, and safety.

### Core Web Vitals (CWV)
- **LCP (Loading)**: < 2.5s
- **INP (Interactivity)**: < 200ms
- **CLS (Stability)**: < 0.1

---

## 2. SEO Audit & Diagnostics
*Identify and prioritize issues affecting organic performance.*

### Audit Framework
- **Crawlability**: Check robots.txt, XML sitemaps, and site architecture.
- **Indexation**: Analyze indexed vs. expected pages, canonicals, and noindex usage.
- **Health Index (0-100)**:
  - 90-100: Excellent
  - 75-89: Good
  - 40-74: Poor/Fair
  - < 40: Critical

### Findings Classification
For every issue identified, report: **Issue**, **Severity** (Critical/High/Med/Low), **Evidence**, and **Recommendation**.

---

## 3. Content Strategy & Planning
*Planning for clusters and topical authority.*

- **Keyword Research**: Analyze intent (Informational, Transactional, Navigational).
- **Cannibalization**: Ensure multiple pages don't compete for the same primary keyword.
- **Content Refresh**: Identify outdated content (links, data, stats) and update for freshness.
- **Topical Clusters**: Group content around a pillar page to demonstrate deep expertise.

---

## 4. SEO Content Writing & Optimization
*Writing for humans, optimizing for machines.*

### Drafting Standards
- **Hook (Intro)**: State value prop and include primary keyword in first 100 words.
- **Density**: 0.5% - 1.5% naturally integrated.
- **Readability**: Grade 8-10 level, short paragraphs (2-3 sentences).
- **Formatting**: Use H2/H3 logically, bullet points, and original examples.

### Meta & Snippets
- **Title Tags**: 50-60 chars, primary keyword in first 30 chars.
- **Meta Descriptions**: 150-160 chars, include CTA and action verbs.
- **Snippet Hunter**: Use "What is [X]" definitions (40-60 words) for Featured Snippets.

---

## 5. Technical SEO & Structure
*Ensuring clarity for crawlers.*

- **Header Hierarchy**: Single H1, logical nesting of H2-H6.
- **Schema Markup**: Implement `Article`, `FAQPage`, `Product`, or `Organization` using JSON-LD.
- **Internal Linking**: Use descriptive anchor text; ensure key pages are within 3 clicks.
- **Mobile-First**: Validate responsive layout and tap target sizing.

---

## 6. Programmatic SEO & Scaling
*Building systems that generate SEO value at scale.*

### System Design
1. **Head Terms**: Broad categories (e.g., "Best [X] in [City]").
2. **Modifiers**: Variables that create long-tail keywords.
3. **Template Design**: Modular blocks that maintain quality for 1,000+ pages.
4. **Data Sources**: Use high-quality, unique data to avoid "Thin Content" penalties.

---

## 🛠️ Execution Protocol

1. **Classify Task**: Is this Audit, Creation, or Fix?
2. **Consult Core Principles**: Check E-E-A-T and CWV constraints.
3. **Execute Draft/Audit**: Follow the specific section guidelines.
4. **Self-Verify**: Check character limits, keyword density, and heading logic.
5. **Final Review**: Does this provide **Genuine Value** to a human? If no, rewrite.
