Free Keyword Density Checker

There is no universally agreed number, but 1–3% is commonly cited as a healthy range. Above 3–4%, content may be flagged as keyword-stuffed by search engines. Focus on natural writing first; density is a secondary check.

Less so than a decade ago. Google's algorithms now use semantic understanding and topical relevance, not just raw density. That said, checking density helps you avoid unintentional over-optimization.

Stop words are typically excluded from density calculations because they are not meaningful keywords. This tool filters them to show you density for content words that actually affect SEO.
