*Principles for sustainable search visibility.*

E-E-A-T Framework

• Experience: Showcase first-hand involvement and original demonstrations.

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• Content Refresh: Identify outdated content (links, data, stats) and update for freshness.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.
