Content Analysis

Keyword Density

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

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

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

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
    }
