Keyword Density Checker
Paste text to see which words and 2-, 3- or 4-word phrases appear most, with counts and density percentages. Ignore common words, set a minimum word length and check one target keyword. It’s a local analysis of your text — not search volume or ranking data.
This tool runs entirely in your browser.

What is the Keyword Density Checker?
Keyword density is the share of a text taken up by a word or phrase: occurrences × words in the phrase ÷ total words × 100. If “coffee beans” appears 6 times in a 600-word article, it covers 12 of 600 words, a density of 2%. Phrase counts stop at sentence breaks, so the end of one sentence and the start of the next never form a fake phrase.
Modern search engines don’t reward a particular density, and repeating a keyword unnaturally can read as spam. The useful questions are simpler: does the page mention its topic clearly, are you over-using one phrase, and are related terms present? This tool answers those for the text you paste; it has no data about search volume, competition or rankings.

Keyword Density Explained: How to Check Word and Phrase Frequency →Frequently asked questions
What is a good keyword density?
There is no ideal number. Write naturally for readers; if one phrase is far above everything else (say 4–5% for a long article), it may read as repetitive.
How is density calculated?
Occurrences × number of words in the phrase ÷ total words × 100. A two-word phrase found 5 times in 500 words has a density of 2%.
Which words are ignored?
With “Ignore common words” on, about 190 English function words (articles, pronouns, prepositions, auxiliaries) are skipped, and phrases that start or end with one are dropped.
Is the Keyword Density Checker free and private?
Yes. The Keyword Density Checker is free, needs no account, and runs entirely in your browser. What you type is never sent to a server or stored.
