Keyword density is the percentage of times a keyword appears in your content relative to the total word count. For example, if a keyword appears 5 times in a 500-word article, the density is 1%.
There is no perfect density, but most SEO experts recommend keeping primary keywords between 1% and 3%. Overusing keywords (keyword stuffing) can trigger search engine penalties.
Stop words are common words like "the," "is," "and" that add little meaning. Excluding them gives you a clearer picture of your content-rich keywords and their actual density.
Multi-word phrases (n-grams) help you find long-tail keywords in your content. These phrases often match how people actually search and can reveal optimization opportunities.
You can paste any amount of text. For large texts over 5,000 words, the analysis runs in a background thread to keep the page responsive. There is no hard limit.
