What Is Keyword Density?

Keyword density is the percentage of times a keyword or phrase appears in a piece of content relative to the total word count. For example, if your target keyword appears 5 times in a 500-word article, the keyword density is 1%.

While Google has moved beyond simple keyword density as a ranking factor, it remains a useful metric for ensuring your content is properly optimized without being over-optimized (keyword stuffing).

Recommended Keyword Density

• Primary keyword: 1-2% density is the sweet spot
• Secondary keywords: 0.5-1% density each
• Over 3%: May trigger keyword stuffing penalties
• Under 0.5%: May not signal relevance strongly enough

Beyond Keyword Density: Semantic SEO

Modern SEO is about topic coverage, not just keyword repetition. Google's algorithms understand synonyms, related terms, and context. Focus on covering your topic comprehensively rather than hitting a specific keyword density number.

Use this checker to identify which terms naturally appear most in your content, then compare that with your target keywords to ensure alignment. If your target keyword doesn't appear in your top terms, you may need to adjust your content.
