What Is Keyword Density?

Keyword density is the percentage of times a keyword appears in your text compared to the total word count. A density of 1–2% is generally considered SEO-optimal — enough to signal relevance without appearing spammy to search engines.

SEO Keyword Density Guidelines

  • Under 0.5%: Keyword may be too sparse — consider using it more naturally
  • 0.5% – 1%: Low but acceptable — good for supporting keywords
  • 1% – 3%: Ideal range — signals relevance without over-optimization
  • Over 3%: Risk of keyword stuffing — search engines may penalize over-optimized content
