How word frequency counter works
Word frequency analysis counts how many times each distinct word appears in a body of text. It is the basis of keyword density checks, text mining, readability analysis, and simple stylometry. The result is usually sorted by frequency so the most common words come first.
This counter splits the text on non-word characters (treating apostrophes as part of a word), folds case by default (so "The" and "the" count together), and counts each token. It returns the total word count, the number of unique words, and a frequency list sorted by count then alphabetically, with each word's percentage of the total. You can keep case sensitivity on and limit the list to the top N words.
Paste your text and click Count. The tool reports the totals and the top words. Use it for keyword density in SEO content, spotting repeated words in writing, and analysing the vocabulary of a document.
