Paste any article and instantly see which keywords dominate it. Our free keyword density checker counts word frequency, calculates density percentages, and ranks your top terms — so you can tell at a glance whether your target keyword is well optimized or overused.
Ideal keyword density is typically 1-2% for your main keyword. This tool strips common stop words so you see the terms that actually matter for SEO.
On-page SEO lives or dies on balance: mention your keyword too rarely and Google may miss what the page is about; stuff it unnaturally and you risk a penalty for spam. Our analyzer strips meaningless stop words, shows exact density percentages, and reveals which terms your content emphasizes most — giving you a data-driven basis for natural, reader-friendly optimization instead of guesswork.
Generally 1–2% for your primary keyword. Much higher starts to look like keyword stuffing, which Google has penalized since the early 2000s.
Yes — common words like 'the', 'and', and 'is' are filtered out so the analysis focuses on meaningful terms that actually describe your topic.
No tool guarantees rankings. But balanced, natural keyword usage is a solid on-page SEO foundation that helps search engines correctly understand what your content covers.
It's smart practice: run a competitor's article through the checker to see which terms they emphasize, then make sure your own content covers the topic at least as thoroughly — ideally better.
