How to Use Keyword Density Checker
Keyword Density Checker — Free Developer Utility
Keyword Density Checker — analyze the word frequency and keyword density percentage of any text for SEO content optimization. Keyword density measures how often a keyword appears in your content relative to the total word count. Over-optimization (keyword stuffing) triggers Google penalties. Under-optimization means your content may not rank for your target terms. The ideal keyword density for primary keywords is roughly 1-2% for the main keyword. Our checker counts every meaningful word after removing common stop words and shows the percentage density for each term, helping you identify over-optimized or under-optimized content before publishing.
