Frequently Asked Questions
What is word frequency analysis?
Word frequency analysis counts how often each word appears in a text. It's used by writers to identify overused words, by SEO professionals to check keyword density, by researchers to analyse large text corpora, and in data science for natural language processing.
What is keyword density?
Keyword density is the percentage of times a target keyword appears in your content relative to total word count. Example: if 'calculator' appears 10 times in a 1,000-word article, density = 1%. Google recommends 1–2% — over-optimisation (keyword stuffing) can hurt rankings.
What are stop words?
Stop words are common words that appear frequently but carry little meaning: the, a, an, is, are, was, were, in, on, at. They're filtered out in word frequency analysis to focus on meaningful content words. This tool lets you toggle stop word filtering on or off.
