Keyword Density Checker
Paste your text to see the most-used words and phrases with their counts and density percentage — with an optional filter for common stop words. Everything runs in your browser.
How to use the keyword density checker
Paste any text — an article, essay, product page or email — and the table updates instantly with the words that appear most often and how heavily each one is used. Switch between single words and 2- or 3-word phrases to spot repeated expressions, and toggle Ignore common words to hide filler like "the" and "and" so the meaningful terms rise to the top. Density is the share of the total word count each term takes up, shown as a percentage.
Use it to check that a page actually emphasises its topic, to catch a word you have over-used, or to tidy up repetitive writing. For a plain count of words, characters and reading time, use the word counter.
Frequently Asked Questions
What is keyword density?
Keyword density is how often a word or phrase appears in a piece of text, expressed as a percentage of the total word count. If a keyword appears 6 times in a 300-word article, its density is 6 ÷ 300 = 2%. It's a rough signal of what a page is about, useful for spotting over-used or missing terms when editing.
What is a good keyword density?
There's no exact target, and modern search engines don't reward a specific number. As a rule of thumb, keeping a main keyword's density in a natural range — often cited as around 1 to 2% — avoids both under-use and keyword stuffing. Write for readers first; use density only to catch words you've leaned on too heavily or forgotten to include.
What are stop words?
Stop words are very common words like the, a, and, of and to that appear in almost any text and rarely carry meaning on their own. Turning on the stop-word filter hides them so the table shows the words and phrases that actually describe your topic.
