What keyword density is — and isn't
Keyword density is the percentage of a page made up of a given word or phrase: the number of times the term appears divided by the total word count. This analyzer breaks your text into 1-, 2-, and 3-word groups (n-grams), filters out common stop words, and ranks what's actually repeated.
What density is not is a ranking lever. Google retired exact-match density as a signal long ago in favor of TF-IDF and semantic models that judge meaning, not repetition. So treat the percentage as a diagnostic, not a target — there is no number you should be 'hitting.' Its real value is the opposite: catching a phrase you've leaned on too hard.
