Keyword Density Checker
Analyze your article's keyword usage instantly. Our free Keyword Density Checker runs locally to help you avoid SEO penalty for 'keyword stuffing' while keeping your drafts private.
What is the Keyword Density Checker?
In SEO, placing your target keyword in an article is important, but overusing it ('keyword stuffing') can result in a severe Google penalty. The ideal density is usually between 1% and 3%. This tool acts as an instant SEO auditor. You paste your raw article text, and it algorithmically calculates the total word count and exactly what percentage of the text is made up of your target keywords. Because writers often check unreleased, proprietary drafts, this tool is built exclusively with client-side JavaScript, ensuring your content is never uploaded to our servers.
