Count word frequency and keyword density in any text.
Updated
Analyze any text to see how often each word appears and its keyword density — each word's percentage share of the total content — ranked with a visual bar. Filter out common stop words for on-page SEO analysis, or keep them for style and readability checks. Copy the full list as CSV to your clipboard.

A word frequency counter lists every distinct word in a piece of text alongside how many times it appears, ranked from most to least common. Keyword density is each word's share of the total: a word used 6 times in 300 words has a density of 2%. This tool tokenizes on runs of letters, digits, and apostrophes, so it works across languages, keeps contractions like don't as one word, and splits hyphenated terms into their parts. You can ignore case, hide 76 common English stop words, and drop words below a minimum length. Density is always calculated against the full word count before filtering, so the percentages stay comparable when stop words are hidden. Results sort by count, then alphabetically, with a relative bar for each word. The screen shows the top 200 words; Copy CSV puts the complete list on your clipboard with word, count, and density columns. Everything runs in your browser.
Keyword density is how often a word appears as a percentage of the total words — count ÷ total words × 100. It's used in on-page SEO to check a page isn't over- or under-using a target keyword.
Turn on 'Ignore common words' to exclude stop words like 'the', 'and', and 'of', so the ranking shows the meaningful keywords in your content.

Because density is always measured against every word in the text, including the stop words you have hidden. That keeps each word's percentage stable whether the filter is on or off, so the visible rows will sum to less than 100% when common words are excluded.
