Keyword Density & N-Gram Analyzer

Analyze text to calculate exact keyword density percentages for 1-word, 2-word, and 3-word combinations. Detect potential over-optimization or keyword stuffing penalties instantly.

⚡ Quick Answer

Keyword density is the percentage of times a keyword appears in a text compared to the total word count. A natural target is typically between 1% and 2.5%.

💡 How It Works

Parses and tokenizes text, eliminates common filler words (when enabled), constructs 1-gram, 2-gram, and 3-gram frequency maps, and calculates the exact ratio against total word count.

✨ Key Features

  • Tokenization with punctuation stripping
  • Sortable frequency and density percentage columns
  • Over-optimization visual warning indicators (>3% threshold)

❓ Frequently Asked Questions

Does Google have an official keyword density percentage requirement?

No. Google uses natural language processing (BERT/MUM/Gemini) to evaluate semantic topical relevance rather than a rigid keyword density score.
