What Is Keyword Density?

Keyword density is the percentage of times a keyword or phrase appears in a text relative to the total word count. It is a fundamental SEO metric that helps content creators ensure their target keywords appear naturally and with appropriate frequency. Over-optimization (keyword stuffing) can trigger search engine penalties, while under-usage means your page may not rank for target terms. The ideal keyword density is generally between 1-3% for primary keywords, with natural variations and synonyms throughout the content.
