About keyword density
This tool analyses your text and shows how often each word and phrase appears, as a percentage of the total — for single words, two-word and three-word phrases. It also reports word count, unique words and reading time. It is a quick way to check your content reads naturally and is not over-optimised. It runs in your browser.
How Keyword Density Checker works
How to use it
- Paste your text or article.
- Switch between 1, 2 and 3-word phrases.
- Review the most frequent terms and their density.
How density is calculated
Keyword density is the number of times a term appears divided by the total number of words, shown as a percentage. Counting two and three-word phrases (n-grams) reveals the key phrases your content actually emphasises, not just single words.
What is a good density?
There is no magic number, but natural writing usually keeps any single keyword well under about 2–3%. Much higher can look like keyword stuffing, which hurts rather than helps. Optionally ignore common stop words to focus on meaningful terms.
