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.

Keyword stuffing is the practice of unnaturally repeating keywords to manipulate rankings. Search engines penalize this. Use this tool to check if any term exceeds 3-4% density, then rewrite those sections to sound more natural.
Both. Single keywords (1-grams) reveal your most-used terms, while 2-gram and 3-gram phrases show how often you use specific long-tail keyword combinations that users actually search for. Balancing both leads to better content optimization.
