Keyword density is an important aspect of SEO (Search Engine Optimization). It refers to the percentage of times a specific keyword appears in a piece of content compared to the total word count. While keyword density used to be a major ranking factor, modern search engines like Google use more sophisticated algorithms. However, maintaining an appropriate keyword density is still important for content relevance.

This keyword density analyzer tool helps you check the frequency of keywords in your content. Simply paste your text and click analyze to see which keywords appear most frequently. This tool is built entirely with client-side technologies: HTML5, CSS3, and Vanilla JavaScript. No data is sent to any server - all processing happens in your browser for maximum privacy and security.

SEO best practices suggest that keyword density should be natural and not forced. Keyword stuffing (overusing keywords) can actually harm your search rankings. Instead, focus on creating high-quality content that naturally incorporates relevant keywords and provides value to your readers.

Use this tool to analyze your content and ensure your keywords are appropriately distributed throughout your text.
