THE BASICS
What Is Keyword Density?
Keyword density is how often a word or phrase appears in a piece of text compared with the total number of words. If a keyword appears 5 times in 500 words, its density is 1%.
There is no magic density that ranks a page. Search engines read for meaning, so the best use of this tool is as a sanity check: make sure your topic is clearly covered, and that nothing is repeated so often it reads unnaturally.

GOOD TO KNOW
A few things, answered.
Quick answers about using the MoSanKit Keyword Density Checker.
There is no ideal number. Many writers see a natural 0.5–2% for a main keyword, but use it as a guide, not a target. Write for readers first.
Repeating a keyword unnaturally — keyword stuffing — can make content hard to read and may be treated as spam. Aim for natural writing.
Two- and three-word phrases are shown only when they appear more than once. Phrases that start or end with a common word are skipped when the filter is on.
Letters and numbers separated by spaces or punctuation. Hyphenated words and contractions such as "don't" count as one word.
Yes for counting. The common-word filter is for English, so turn it off for other languages.
No. Everything is analysed in your browser.
