Key Components of a Technical SEO Audit Using Python

To automate a powerful technical SEO audit, your Python script should check key website elements, including:

1. HTTP Status Codes –⁤ Identify broken links ‌and server errors.
2. Page Titles & Meta Descriptions – Check length, ‍existence, and uniqueness.
3. Heading Tags ⁤(H1,​ H2) – Assess usage and structure.
4. Internal ​Linking – Analyze link structure and depth.
5. Page Load Speed – Monitor site performance metrics.
6. mobile-Friendliness –⁢ Ensure responsive design and usability⁣ on all devices.
7. Robots.txt and sitemap.xml – Verify configurations and accessibility.

Step-by-Step Guide to Creating Your Python SEO Audit Script

1. Setup Your Environment

Start by ⁣setting up⁣ Python and essential SEO ​libraries:

• Install Python 3.x if not ​already installed.
• Use pip to install libraries:

pip install requests beautifulsoup4 pandas matplotlib

2. Check ​HTTP Status ⁤Codes

Detect broken ​URLs and server issues using the requests module.

import requests



def check_status(url):

    try:

        response = requests.get(url,timeout=5)

        return response.status_code

    except requests.RequestException:

        return None

3. extract‍ and Analyze Meta Tags and Headings

Use BeautifulSoup to scrape and analyze page titles,meta descriptions,and header ⁤tags.

from bs4 import BeautifulSoup



def analyze_meta_and_headings(html):

    soup = BeautifulSoup(html, 'html.parser')

    title = soup.title.string if soup.title else 'No Title'

    meta_desc_tag = soup.find('meta', attrs={'name':'description'})

    meta_desc = meta_desc_tag['content'] if meta_desc_tag else 'No meta Description'

    h1_tags = [h.get_text(strip=True) for h in soup.find_all('h1')]

    h2_tags = [h.get_text(strip=True) for h in soup.find_all('h2')]

    return {

        'title': title,

        'meta_description': meta_desc,

        'h1_count': len(h1_tags),

        'h2_count': len(h2_tags)

    }

4. Crawl Internal Links

Gather internal links to analyze website structure and crawl depth.

def get_internal_links(html, base_url):

    soup = BeautifulSoup(html, 'html.parser')

    internal_links = set()

    for link in soup.find_all('a', href=True):

        href = link['href']

        if href.startswith('/') or base_url in href:

            internal_links.add(href if href.startswith('http') else base_url + href)

    return internal_links

5.⁢ Save Results and Generate Report

Use pandas to‌ organize audit findings and export as‍ CSV or Excel for deeper‍ analysis.

import pandas as pd



data = [

    {'URL': 'https://example.com', 'Status': 200, 'Title': 'Example Domain', 'Meta Description': 'No Meta Description', 'H1 Count': 1, 'H2 Count': 0},

    # Add more page data here

]



df = pd.DataFrame(data)

df.to_csv('seo_audit_report.csv', index=False)

Example Python SEO Audit Workflow

1. Input the website’s root URL.
2. Fetch the homepage and run check_status().
3. Analyze meta data and headings.
4. Extract internal links.
5. Recursively⁣ crawl internal links​ with controlled depth.
6. Compile results into a spreadsheet or ‍HTML report.
