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. It's an important SEO metric that helps you optimize content without over-optimization (keyword stuffing).

📊 Optimal Density

  • Primary Keyword: 1-2% density is ideal
  • Secondary Keywords: 0.5-1% works well
  • Long-tail Phrases: Natural occurrence, don't force
  • Avoid Stuffing: Over 3% looks spammy to Google
  • Context Matters: Use synonyms and related terms

🎯 Analysis Features

  • 2-Word Phrases: Find natural keyword combinations
  • 3-Word Phrases: Discover long-tail opportunities
  • Stop Word Filter: Focus on meaningful keywords
  • Real-time Analysis: Instant results as you type

How to Use This Tool

  1. Paste your article, blog post, or webpage content into the text area
  2. Toggle stop words filter to include/exclude common words like "the", "and", "is"
  3. Review the analysis across three tabs: single words, 2-word phrases, and 3-word phrases
  4. Check if your target keywords appear with optimal density (1-2%)
  5. Adjust your content if keywords are over-used (stuffing) or under-used
