Free Keyword Density Checker – Analyze Keyword Usage

📏 Keyword Density Guidelines

• Optimal Density: 1–2% for your primary keyword (appears 1–2 times per 100 words)
• Under-optimization: Less than 0.5% may signal Google the keyword isn't relevant
• Over-optimization: More than 3–4% may trigger keyword stuffing penalties
• Natural Usage: Focus on natural language, not exact keyword density numbers
• LSI Keywords: Use related keywords and synonyms to avoid repetition
• Long-tail Keywords: 2-word and 3-word phrases often convert better than single words

🛠️ How to Use This Tool

• Paste your content or enter a URL to analyze
• Optionally enter your target keyword for specific analysis
• Review 1-word, 2-word, and 3-word keyword frequencies
• Check density percentages (ideal: 1–2% for main keyword)
• Follow recommendations to optimize without keyword stuffing
• Use for blog posts, product descriptions, and landing pages

📖 What is Keyword Density?

Keyword density is the percentage of times a keyword or phrase appears in your content compared to the total word count. For example, if your keyword appears 5 times in a 500-word article, the density is 1% (5 ÷ 500 × 100). While Google no longer relies heavily on exact keyword density, maintaining natural keyword usage (1–2%) helps search engines understand your content topic without triggering over-optimization penalties. Modern SEO focuses on topic relevance, user intent, and semantic keywords rather than hitting a specific density percentage.
