About Keyword Density Checker

Keyword density — how frequently a term appears relative to a page's total word count — used to be a heavily gamed SEO metric, but it's still a useful sanity check today: content that's wildly over-optimized for one phrase can read awkwardly to actual visitors, while content that never mentions its target topic clearly might be under-optimized. This tool breaks down your text's word frequency and density percentage so you can see exactly where you land.

Paste in any block of text and get back a ranked table of the most frequent meaningful words (filtering out connectors like 'the' and 'and'), each with its raw count and density percentage relative to total word count. This makes it easy to spot unintentional overuse of a word, or confirm your target keyword actually appears often enough to signal relevance.

There's no single 'correct' density percentage — search engines don't publish a target ratio, and chasing one can hurt readability more than it helps rankings. Use this as a diagnostic to catch obvious over- or under-optimization, not as a formula to hit exactly.

How it works

1. Paste your content. Any article, page copy, or product description.
2. Review the frequency table. See every significant word ranked by count and density.
3. Adjust if needed. Rewrite sections that are over- or under-using a term.
