Use keyword density when you're writing SEO-targeted content and want to verify your focus keyword is present (but not over-used) in the final draft. Pair with the n-gram analyzer to see what phrases actually dominate the page.
Keyword density is a focused SEO tool. The Word Frequency tool gives raw counts; the N-gram analyzer surfaces phrases without an SEO frame. Use keyword density when "% density" is the metric you need to defend.
Keyword density is the count of a word or phrase divided by the total number of countable words, expressed as a percentage.
For SEO, target 1–3% density for your focus phrase. Above 5% is flagged here as potential keyword stuffing — Google penalizes obviously over-optimized text.
The tool computes 1-word, 2-word, or 3-word phrase density separately. Stopwords and short words are filterable so the top entries surface meaningful content.
1–3% for your focus phrase. Above 5% risks being flagged as keyword stuffing by Google.
Not as a direct ranking signal, but extreme over-optimization triggers spam filters. Modern SEO weights topical coverage and semantic relevance more than density.
Single-word density catches your focus keyword; phrase density catches the long-tail terms (e.g., "remote work productivity") that often drive more qualified traffic.
입력
500-word blog post about "remote work productivity tips".
출력
"remote work" appears 14 times (2.8% density) · "productivity" 9 times (1.8%) · "tips" 7 times (1.4%).
For a focus phrase, 1–3% density is the modern best practice. Anything above 5% risks being flagged as keyword stuffing by Google's ranking signals.
