🔍 Keyword Density Analyzer
Analyze keyword frequency and density with 1-gram, 2-gram, and 3-gram tables. Spot over-optimization and get actionable recommendations.
How to Use the Keyword Density Analyzer
Paste your content into the textarea, optionally enter a target keyword, and click Analyze. The tool breaks your text into single words (1-grams), two-word phrases (2-grams), and three-word phrases (3-grams), counting each occurrence and calculating its density as a percentage of total words.
- Stop words filter removes common words like "the", "is", "and" so you see only meaningful terms.
- Target keyword tells you the exact count, density, and whether it falls in the ideal 1–3% range.
- Color-coded bars: green (1–3% ideal), yellow (3–4% borderline), red (>4% over-optimized).
What Is Keyword Density?
Keyword density is calculated as: (keyword count ÷ total word count) × 100. A keyword density of 2% means the keyword appears twice for every 100 words. Search engines use density as one of many signals to understand page relevance, but over-stuffing keywords can lead to ranking penalties.
Best Practices for Keyword Usage
- Aim for 1–3% density for your primary keyword.
- Use natural language — write for humans first, search engines second.
- Include semantically related terms and synonyms (LSI keywords).
- Avoid repeating the exact same phrase excessively — Google's algorithms detect keyword stuffing.
- Analyze the top 2-gram and 3-gram phrases to discover unintentional repetition.
