## Content Analysis

### Keyword Density

```python
import re
from collections import Counter

def keyword_density(text, keyword):
    words = re.findall(r'\b\w+\b', text.lower())
    keyword_count = text.lower().count(keyword.lower())
    density = (keyword_count / len(words)) * 100
    return {
        "keyword": keyword,
        "count": keyword_count,
        "total_words": len(words),
        "density": f"{density:.2f}%"
    }

# Target: 1-2% density
```

### Readability Score

```python
import textstat

text = "Your content here..."

flesch = textstat.flesch_reading_ease(text)
# 90-100: Very Easy
# 60-70: Standard
# 0-30: Very Difficult

grade = textstat.flesch_kincaid_grade(text)
# Target: 8-9 for general audience
```

### Content Structure Analysis

```python
from bs4 import BeautifulSoup

def analyze_headings(html):
    soup = BeautifulSoup(html, 'html.parser')
    headings = {
        'h1': soup.find_all('h1'),
        'h2': soup.find_all('h2'),
        'h3': soup.find_all('h3'),
    }
    
    issues = []
    if len(headings['h1']) == 0:
        issues.append("Missing H1 tag")
    elif len(headings['h1']) > 1:
        issues.append("Multiple H1 tags (should be one)")
    
    return {
        "counts": {k: len(v) for k, v in headings.items()},
        "issues": issues
    }
```

## Meta Tag Analysis

### Extract Meta Tags

```python
from bs4 import BeautifulSoup
import requests

def audit_meta_tags(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    title = soup.find('title')
    description = soup.find('meta', attrs={'name': 'description'})
    keywords = soup.find('meta', attrs={'name': 'keywords'})
    
    issues = []
    
    if not title or len(title.text) < 30:
        issues.append("Title too short or missing")
    elif len(title.text) > 60:
        issues.append("Title too long (>60 chars)")
    
    if not description:
        issues.append("Meta description missing")
    elif len(description.get('content', '')) < 120:
        issues.append("Meta description too short")
    elif len(description.get('content', '')) > 160:
        issues.append("Meta description too long")
    
    return {
        "title": title.text if title else None,
        "description": description.get('content') if description else None,
        "issues": issues
    }
```

## Structured Data Check

### Validate Schema Markup

```bash
# Using Google's Rich Results Test
curl "https://searchconsole.googleapis.com/v1/urlTestingTools/richResultsTest:run" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}'
```

### Common Schema Types

```json
// Article
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Title",
  "author": {"@type": "Person", "name": "Author"},
  "datePublished": "2026-01-01"
}

// Local Business
{
  "@context": "https://schema.org",
  "@type": "LocalBusiness",
  "name": "Business Name",
  "address": {"@type": "PostalAddress", "streetAddress": "123 Main"},
  "telephone": "+1-555-555-5555"
}

// FAQ
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "Question?",
    "acceptedAnswer": {"@type": "Answer", "text": "Answer"}
  }]
}
```

## Competitor Analysis

### Compare Page Metrics

```python
import requests
from bs4 import BeautifulSoup

def compare_seo(target_url, competitor_url):
    def get_metrics(url):
        r = requests.get(url)
        soup = BeautifulSoup(r.text, 'html.parser')
        return {
            "title_len": len(soup.find('title').text) if soup.find('title') else 0,
            "h1_count": len(soup.find_all('h1')),
            "h2_count": len(soup.find_all('h2')),
            "word_count": len(soup.get_text().split()),
            "images": len(soup.find_all('img')),
            "images_no_alt": len([i for i in soup.find_all('img') if not i.get('alt')])
        }
    
    return {
        "target": get_metrics(target_url),
        "competitor": get_metrics(competitor_url)
    }
```
