How density is measured
Each term's density is how often it appears as a share of all the words (or phrases) in the text:
density = term count ÷ total words × 100%
For natural writing, most individual keywords sit around 1–2%. Very high density can read as "keyword stuffing". Stop words (the, and, of…) are left out of the single-word list by default so the real topics surface; they still count toward the total, so hiding them doesn't change a density. Everything is counted in your browser.

How it works
For natural writing most individual keywords sit around 1–2%. Common stop words like the and of are left out of the list by default so the real topics stand out; they still count toward the total, so hiding them does not change a density.
density = term count ÷ total words × 100
Understanding your result
For natural writing most individual keywords land around 1 to 2 percent; far above that reads as keyword stuffing and can hurt rather than help. Use it to confirm your main topic actually appears, and to spot accidental over-repetition, but write for the reader first since modern search ranks on meaning and coverage, not raw density.
Example
A word used 5 times in 250 has a 2% density.
