What Is Keyword Density?
Keyword density is the ratio of a word to the total word count of a text (word frequency ÷ total words × 100). In SEO this ratio indicates how focused your content is on a topic. This tool analyses your text, ranks the most frequent words and computes each one's density; optionally it excludes filler words like "and, the, this".
What Density Is Ideal?
Modern SEO has no fixed "ideal ratio"; Google now looks at topical completeness and user intent far more than keyword count. Still, repeating a word so often that it looks unnatural (over-optimisation / keyword stuffing) annoys readers and risks a penalty. Practical rule: your target keyword should appear naturally, usually around 1–2%, supported by synonyms and related terms.
How to Use It
Paste your text, choose the minimum word length (3+ is recommended to drop short conjunctions) and tick exclude filler words. The result shows whether your target keyword appears at the frequency you expect and which words dominate. To produce strong content for GEO (generative-AI visibility) and SEO, see our SEO optimisation service and our Word Counter for text length.
