SEO (Search Engine Optimization) analysis is an essential step in measuring a website’s performance on search engines and improving that performance. An SEO analysis evaluates the technical, content, and external link quality of your site, identifying areas for improvement. In this article, we will thoroughly examine what to focus on when creating an SEO analysis script, which metrics it should include, and how to perform these analyses using code examples.

What Does an SEO Analysis Include?

An SEO analysis script should include the following key areas:

  • Technical SEO Analysis
  • Content SEO (On-Page SEO)
  • External Links (Backlink) Analysis
  • Page Speed and Mobile Compatibility
  • Keyword Analysis

1. Technical SEO Analysis

Technical SEO ensures that a website is easily crawled and indexed by search engine bots. The essential metrics for checking technical SEO in your SEO script are:

  • Page Title (Title Tag) and Meta Descriptions: Check whether each page has optimized titles and meta descriptions.
  • URL Structure: Ensure the use of SEO-friendly, clean URL structures.
  • H1 Tags: Verify that each page has one H1 tag and it is used correctly.
  • Sitemap and Robots.txt: Check if the sitemap and robots.txt files exist.
  • SSL (HTTPS) Status: Analyze whether the site is secured with HTTPS.

def teknik_seo_analizi(url):
    # Fetch the URL using GET request
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')

    # Check the Title Tag
    title_tag = soup.find('title')
    title = title_tag.text if title_tag else "Title not found"
    print(f"Page Title: {title}")

    # Check Meta Description
    meta_description = soup.find('meta', attrs={'name': 'description'})
    description = meta_description['content'] if meta_description else "Meta description not found"
    print(f"Meta Description: {description}")

    # Check H1 Tag
    h1_tag = soup.find('h1')
    h1 = h1_tag.text if h1_tag else "H1 tag not found"
    print(f"H1 Tag: {h1}")

    # SSL Check
    if url.startswith('https'):
        print(f"{url} uses secure (SSL) protocol.")
    else:
        print(f"{url} is not secure! SSL (https) is not used.")

2. Content SEO (On-Page SEO)

Content SEO helps search engines understand and assess your website’s content. Content SEO should include these metrics:

  • Keyword Density: Check whether the content contains targeted keywords and the keyword density ratio.
  • Image Optimization: Ensure that images have appropriate alt tags.
  • Internal Linking: Check whether there are links between pages.

You can perform a simple keyword analysis with Python:

pythonKodu kopyalafrom collections import Counter
import requests
from bs4 import BeautifulSoup

def anahtar_kelime_analizi(url, hedef_kelime):
    # Fetch the page content
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    # Get all text from the page
    text = soup.get_text()
    
    # Calculate the density of the target keyword
    words = text.split()
    word_count = Counter(words)
    target_word_count = word_count[hedef_kelime]
    total_word_count = len(words)
    
    # Calculate keyword density
    keyword_density = (target_word_count / total_word_count) * 100
    print(f"Keyword Density ('{hedef_kelime}'): {keyword_density:.2f}%")

anahtar_kelime_analizi("https://your-example-site.com", "SEO")

3. External Links (Backlink) Analysis

Backlinks represent the links that other websites provide to your site and directly impact your SEO performance. To analyze backlinks, you can use APIs from SEO tools like Moz, Ahrefs, or SEMrush. These tools provide data on the number, quality, and sources of backlinks to your site.

Since it is challenging to conduct backlink analysis with free tools, third-party APIs are generally used in this section.

4. Page Speed and Mobile Compatibility

It is well known that Google uses page speed and mobile compatibility as significant factors in SEO rankings. You can use the Google PageSpeed Insights API to measure page speed and receive recommendations to improve user experience.

Here is a Python script example for conducting a speed test using the PageSpeed Insights API:

pythonKodu kopyalaimport requests

def sayfa_hizi_analizi(url, api_key):
    api_url = f"https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url={url}&key={api_key}"
    response = requests.get(api_url)
    data = response.json()
    
    # Performance score
    performance = data['lighthouseResult']['categories']['performance']['score'] * 100
    print(f"Page Performance Score: {performance}/100")
    
# Add your Google API key here
api_key = 'YOUR_API_KEY'
sayfa_hizi_analizi("https://your-example-site.com", api_key)

5. Keyword Analysis

Keyword analysis is one of the most crucial components of SEO, helping you understand which keywords you should target and where your site ranks for certain keywords. In this section, you can pull data using Google Search Console or third-party APIs for analysis.

Conclusion

Developing an SEO analysis script requires integrating various metrics and tools. Key elements like technical SEO, content optimization, backlink analysis, page speed, and keyword analysis are essential for a thorough SEO evaluation. Writing simple SEO analysis scripts with Python is possible, and these scripts can be enhanced using various APIs.

By following the steps outlined in this article, you can develop your own SEO analysis software and make data-driven decisions to improve your website’s SEO performance.
