Keyword density checker
Paste an article or a page's copy to see which words and phrases you use most. Each row shows the phrase, how many times it appears and what percentage of all the words in the text that is.
Runs in your browser: nothing you enter is sent anywhere.
How to use it
- Paste your text.
- Choose whether to count single words or phrases of two or three words.
- Switch the stop-word filter on or off and set how many rows to show.
- Copy the list if you want to paste it into a spreadsheet; columns are separated by tabs.
How it works
The text is lowercased and split into words. Every run of the chosen length is counted, rows are sorted by count (ties alphabetically), and each count is divided by the total number of words.
Worked example
In “red apple, red apple, green pear” there are 6 words. The phrase “red apple” appears twice, so its density is 2 ÷ 6 = 33.33%.
Tips
Phrases are counted as overlapping runs, so a word can be part of several phrases. A very high share for one word usually reads as repetition to a human reader, too.
Frequently asked questions
How is keyword density calculated?
Density = number of times a phrase appears ÷ total number of words in the text × 100. The total counts every word, including stop words, even when they are hidden from the list.
What are stop words?
Very common words such as the, of, and, to and is. With the filter on, a single word is skipped if it is a stop word, and a phrase is skipped if it starts or ends with one. The list is a short English one; for other languages turn the filter off.
What density is ideal for SEO?
There is no magic number. Search engines do not publish a target density, so use this tool to spot unnatural repetition and to see which topics your text really covers, and write for readers first.
Which text counts as a word?
Runs of letters and digits, with an apostrophe inside a word kept ("don't"). Case is ignored, so Coffee and coffee count together.
