The Keyword Density Checker analyzes any text and shows exactly how often each word and phrase appears — the key metric SEO writers use to avoid keyword stuffing and keep content natural. Paste your article, blog post, or product description and get instant density percentages for single words, two-word, and three-word phrases.
Search engines penalize pages that repeat the same keyword unnaturally. This tool highlights your top keywords, shows their density, and helps you balance optimization with readability. Bloggers, copywriters, and SEO professionals use it before publishing to make sure every page hits the sweet spot.
Like every tool here, the Keyword Density Checker works 100% in your browser. Your files are processed on your own device and never uploaded to any server — which also means it is fast, private, and free to use.
Keyword density is the percentage of times a keyword appears in your text compared to the total word count. For example, if a 100-word article mentions "free tools" 3 times, its density is 3%.
Most SEO experts recommend a natural density of 1-2% for your main keyword. Higher than 3% can look like keyword stuffing to Google. Write naturally first, then check.
No. All analysis happens in your browser — your text never leaves your device.
