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

"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.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
}
