Keyword Density Checker

Keyword density is the percentage of times a keyword or phrase appears on a page relative to the total word count. For example, if a word appears 5 times in a 500-word page, its density is 1%. It was historically used as an SEO ranking signal, though modern search engines use much more sophisticated relevance models.

There is no single ideal number, but most SEO practitioners recommend keeping primary keyword density between 0.5% and 2.5%. Densities above 4–5% are often associated with keyword stuffing and can trigger ranking penalties. The most important thing is that content reads naturally for humans.

Keyword density alone is not a direct Google ranking factor, but keyword relevance is. Using your target keyword and semantically related terms at a natural frequency signals topical relevance. Over-stuffing keywords is actively harmful — Google's Panda and Penguin algorithms penalize unnatural repetition.

You can analyze any publicly accessible URL that does not block crawlers. Pages behind authentication, paywalls, or aggressive bot-detection may fail to load. Alternatively, paste the page text directly into the text mode to bypass fetching entirely.
