What is keyword density?
Keyword density is how often a specific word or phrase appears in a piece of text, expressed as a percentage of the total word count. It is calculated as occurrences ÷ total words × 100. For example, if the word "marketing" appears 5 times in a 500-word article, its density is 1%. Matching is case-insensitive, so "Marketing" and "marketing" are counted together.
Why it matters
Writers and SEO specialists use keyword density to avoid both extremes: too little, and the topic is unclear; too much, and the text reads as unnatural "keyword stuffing" that search engines may penalise. As a rough guide, a density of around 1–2% is usually considered natural for a primary keyword, though there is no universal rule — readability and relevance matter more than any exact number.
The top words table lists the 15 most frequent words (case-insensitive) so you can see what your text is actually about at a glance. Common function words such as "the", "and" and "of" will naturally rank high in English; focus on the content words below them. To count the total words, characters and sentences, use the main word counter. To reformat the text, try the case converter.
