```

### 2. On-Page Elements Checklist

| Meta Description | CTA + keyword, 150-160 chars | 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

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

| Expertise | Author bios, credentials, detailed technical knowledge |
| Authoritativeness | Citations, backlinks, brand mentions, awards |

**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
