Count which words and phrases a text actually leans on, as a share of the whole.

What density actually measures
Density is how often a word or phrase appears as a share of the total. It is a description of what a text leans on — useful for checking that a page is about what you think it is about, and for spotting a word you have used forty times without noticing.
The denominator matters and is easy to get wrong. A hundred words contain ninety-nine two-word phrases, not a hundred, so a phrase count divided by the word count understates every row. This divides by the number of phrases of the length being counted.
On chasing a target percentage
There is no density figure that ranks a page. Search engines stopped counting repetitions as a relevance signal long ago, and writing to hit a number produces text that reads like it was written to hit a number. Use this to find accidental repetition, not to manufacture deliberate repetition.
Frequently asked questions
Why are "the" and "and" missing?
Common words are dropped by default for single-word counts, because they crowd out the words that carry meaning. Turn the option off to see them. For multi-word phrases they are always kept — they are part of the phrase.
