Keyword Density Checker

Paste an article to see its word count, reading time, unique words, and the top 20 keywords by frequency with percent density. Optionally enter a target keyword to check whether it falls in the healthy 0.5 – 3 % range — too low looks thin, too high looks spammy. A stopwords toggle filters common filler words for a cleaner top-terms list.

Useful for on-page SEO and long-form writing. Pair with readability score checker to keep copy approachable, or word counter for a quick length check.
