Keyword Density for Content Optimization

What Is the Ideal Keyword Density?

There's no magic number — but there are clear danger zones.

  • Above 3% reads unnaturally and risks over-optimization flags
  • Below 0.5% may not signal relevance strongly enough
  • Google's algorithm leak confirmed they track a KeywordStuffingScore internally
  • This checker shows frequency, occurrence counts, and density for all phrases

N-Gram Analysis: One-Word, Two-Word, and Three-Word Phrases

Single-word frequency is just the start — multi-word phrases reveal what your content is actually about.

  • If your target phrase never appears in top trigrams, you may be drifting off topic
  • Stop words are filtered automatically for cleaner analysis
  • Verify on-page SEO targets the right long-tail and LSI keywords naturally
  • Avoid forcing keyword optimization that hurts readability
