Core Analysis Areas

1. Target Keywords Analysis

• Calculate keyword density (target: 1-2%)

• Flag keyword stuffing issues

2. Content Structure

• Check keyword usage in headings
• Evaluate paragraph length (target: <150 words)
• Assess overall scannability
• Review content organization

3. Readability Metrics

// Readability scoring example
const readabilityMetrics = {
  fleschScore: 65,           // Target: 60-70
  gradeLevel: 8,             // Target: 7-9
  avgSentenceLength: 18,     // Target: <20 words
  passiveVoice: 5,           // Target: <10%
  transitionWords: 30        // Target: >30%
};

Key Metrics:

• Flesch Reading Ease score (60-70 ideal)
• Grade level estimation
• Average sentence length (<20 words)
• Passive voice percentage (minimize)
• Transition word usage

4. Technical SEO Elements

| Element | Recommendation |

|---------|----------------|

| Meta Title | 50-60 characters with primary keyword |

| Meta Description | 150-160 characters, compelling with keyword |

| URL Slug | Short, keyword-rich, hyphen-separated |

| Image Alt Text | Descriptive with natural keyword usage |

Organize findings into prioritized action items based on impact and implementation effort.
