What Is Keyword Density?

Keyword density is the percentage of times a word or phrase appears relative to the total word count. The formula is: (keyword count ÷ total words) × 100. Most SEO experts recommend keeping primary keywords between 1–3% density to avoid both under-optimization and keyword stuffing.

This tool analyzes single keywords, 2-word phrases (bigrams), and 3-word phrases (trigrams) separately. Common stop words are filtered out for meaningful results.
