Free online Keyword Density tool — results appear instantly in your browser. No signup required.
Keyword Density Checker analyzes any piece of content and shows how frequently each word appears. It also calculates the density of a focus keyword you specify. Maintaining a natural keyword density (usually 1–2%) helps your content rank better while avoiding keyword stuffing penalties. Useful for SEO writers, content editors and students who want data-driven insights into their writing. The tool produces a clean table of the most used words ranked by frequency, plus the exact count and percentage of your chosen focus keyword. All analysis happens locally in the browser so your draft never leaves your computer. By reviewing the results you can decide whether to add more instances of a target keyword, reduce overuse of certain terms, or simply confirm that the language feels natural. This makes the checker a practical companion during the editing stage of any SEO-focused article.
