In the world of search engine optimization (SEO), keyword density plays a crucial role in improving the visibility and ranking of a website. By understanding the frequency and distribution of relevant keywords within a blog post, website owners and content creators can optimize their content to attract more organic traffic. In this article, I'll explore a Python script that automates the process of analyzing keyword density in blog posts, enabling efficient SEO optimization.

Understanding Keyword Density

Keyword density refers to the percentage of times a specific keyword appears in a given text compared to the total word count. It helps search engines determine the relevance and topicality of a webpage. By maintaining an optimal keyword density, you can enhance your chances of ranking higher in search engine results pages (SERPs) for targeted queries.

The Python Script

To simplify the task of analyzing keyword density, I have developed a Python script that efficiently calculates the density of specified keywords within a blog post. The script utilizes regular expressions and string manipulation techniques to extract and process the text data.

import re
from collections import Counter

def calculate_keyword_density(text, keywords):
    # Remove special characters and convert to lowercase
    cleaned_text = re.sub(r'[^a-zA-Z0-9\s]', '', text).lower()
    words = cleaned_text.split()
    total_words = len(words)

    # Count the occurrences of each keyword
    keyword_counts = Counter(words)
    keyword_density = {}

    for keyword in keywords:
        count = keyword_counts.get(keyword, 0)
        density = (count / total_words) * 100
        keyword_density[keyword] = density

    return keyword_density
