## Core Guidance

### 1. On-Page Optimization Process
```
Target Keyword -> Intent Analysis -> Content Structure -> Meta Tags -> Heading Hierarchy -> Body Optimization -> Internal Links -> Schema -> Publish -> Monitor Rankings
```

### 2. On-Page Elements Checklist

| Element | Best Practice | Priority |
|---------|-------------|----------|
| Title Tag | Primary keyword + modifier, 50-60 chars | Critical |
| Meta Description | CTA + keyword, 150-160 chars | High |
| H1 | One per page, contains primary keyword | Critical |
| H2-H6 | Logical hierarchy, include secondary keywords | High |
| URL Slug | Short, descriptive, contains keyword | High |
| First Paragraph | Primary keyword within first 100 words | High |
| Image Alt Text | Descriptive, keyword-relevant | Medium |
| Internal Links | 3-5 relevant internal links per page | High |
| External Links | 1-3 authoritative external references | Medium |

### 3. Title Tag Formulas

| Formula | Pattern | Example |
|---------|---------|---------|
| Keyword + Modifier | "[Keyword]: [Modifier]" | "Email Marketing: Complete Guide for 2026" |
| Number + Keyword | "[N] [Keyword] [Benefit]" | "15 SEO Strategies That Actually Work" |
| How-to | "How to [Keyword] [Result]" | "How to Improve Conversion Rates by 50%" |
| Year + Topic | "[Keyword] in [Year]: [Value]" | "Content Marketing in 2026: What's Changed" |
| Question | "[Question with keyword]?" | "Is Your SEO Strategy Ready for AI Search?" |

### 4. Content Quality Framework

| Factor | Assessment Criteria | Score Weight |
|--------|-------------------|-------------|
| Comprehensiveness | Covers topic thoroughly, answers likely questions | 25% |
| Uniqueness | Original insights, data, or perspective | 20% |
| Accuracy | Factually correct, up-to-date information | 20% |
| Readability | Clear writing, proper formatting, scannable | 15% |
| Engagement | Keeps readers on page, encourages interaction | 10% |
| Actionability | Practical takeaways, clear next steps | 10% |

### 5. E-E-A-T Signal Optimization

| Signal | Implementation |
|--------|---------------|
| Experience | First-hand examples, case studies, screenshots |
| Expertise | Author bios, credentials, detailed technical knowledge |
| Authoritativeness | Citations, backlinks, brand mentions, awards |
| Trustworthiness | HTTPS, clear policies, contact info, reviews |

**Page-Level E-E-A-T**:
- Author byline with bio and credentials
- Sources cited and linked
- Last updated date shown
- Clear editorial policy
- Expert review attribution

### 6. Content Gap Analysis

```
Step 1: Identify competitor pages ranking for target keywords
Step 2: List topics/subtopics covered by competitors but not by us
Step 3: Evaluate each gap:
  - Search volume potential
  - Difficulty to rank
  - Business relevance
  - Content type needed (blog, guide, tool, comparison)
Step 4: Prioritize by: volume * (1/difficulty) * relevance
Step 5: Map to content calendar
```

### 7. Content Refresh Strategy

| Signal | Action | Expected Impact |
|--------|--------|----------------|
| Ranking drop (positions 4-20) | Update stats, add new sections | Recover rankings |
| Stale content (>12 months) | Refresh data, update examples | Maintain rankings |
| Thin content (<500 words) | Expand depth, add media | Improve rankings |
| Keyword cannibalization | Consolidate or differentiate | Resolve confusion |
| High impressions, low CTR | Rewrite title/meta description | Improve CTR |

### 8. Content Structure Template

```
[Title Tag: Primary Keyword + Modifier (50-60 chars)]
[Meta Description: CTA + keyword (150-160 chars)]

# H1: Primary Keyword Variation

[Introduction: Hook + context + primary keyword in first 100 words]

## H2: First Major Subtopic

## H2: FAQ Section (optional, for schema)
### Q: [Common question]?
A: [Concise answer]

## H2: Conclusion / Key Takeaways

## Rationalizations
> 이 절은 참고 자료다 — 아래 변명·반박은 모델이 작업 중 스스로 지름길을 점검하는 데 쓰고, 사용자에게 묻는 질문 목록이나 별도 게이트로 쓰지 않는다. 반박에 비추어 스스로 바로잡을 수 없으면 이 스킬의 Step·Checkpoint 규칙을 따른다.

The following table captures common excuses agents make to skip the rigor of this marketing practice, paired with factual rebuttals.

| Excuse | Rebuttal |
|--------|----------|
| "Just stuff the keyword a few more times." | Keyword density over ~2% triggers over-optimization penalties and hurts readability; semantic coverage beats raw repetition. |
| "Meta descriptions don't affect rankings, skip them." | Meta descriptions drive CTR from SERP, which is an indirect ranking signal; missing descriptions cede CTR to competitors. |
| "H1-H6 hierarchy is a visual choice." | Heading structure is parsed by crawlers for topical outline; skipping levels or using multiple H1s breaks topical signals and accessibility. |
| "E-E-A-T is only for YMYL sites." | Google applies E-E-A-T signals (author bios, citations, experience markers) site-wide since 2022; lacking them caps ranking ceiling. |
| "Content length guarantees ranking." | Word count correlates with coverage, not causation; 800 focused words beat 3000 padded words on intent match. |
