About Keyword Density Checker
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. Too high a density looks like keyword stuffing to search engines; too low means you may not be signalling the topic clearly. Our keyword density checker analyses your text and shows every word and phrase along with its frequency count and density percentage. Set a target keyword to see its exact density, get word frequency rankings, and identify phrases to optimise. Recommended keyword density for SEO is typically 1-3% for your primary keyword.
