About Keyword Density
Keyword Density is a free, browser-based tool that analyzes your text for keyword frequency and density. Keyword density is the percentage of times a keyword or phrase appears in your text compared to the total word count. This metric helps you optimize your content for SEO by ensuring you're using your target keywords effectively without overusing them (keyword stuffing). Simply paste your text, enter your target keywords, and get an instant analysis showing keyword frequency, density percentage, and distribution. You can analyze multiple keywords at once and get recommendations for optimal density. Everything runs locally in your browser, so your text is never uploaded to a server. There's no sign-up, no watermark, and no limit — just open Keyword Density, enter your text and keywords, and get instant analysis. Perfect for SEO specialists, content creators, marketers, and anyone who wants to optimize their content for search engines.

Focus on Primary Keywords
Prioritize your primary target keywords and ensure they have appropriate density.
Avoid Keyword Stuffing
Keep keyword density under 5% to avoid keyword stuffing penalties from search engines.
Check Distribution
Ensure keywords are distributed naturally throughout your content, not clustered in one area.
Use Long-Tail Keywords
Include long-tail keywords (3+ word phrases) for better targeting and lower competition.
Natural Language
Write naturally and include keywords where they fit contextually, not forced.
Write for Users First
Optimize for users first, search engines second. Keyword density should support good content, not replace it.
Monitor Competitors
