How density is measured

Each term's density is how often it appears as a share of all the terms counted:

density = term count ÷ total terms × 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 ignored by default for single words so the real topics surface. Everything is counted in your browser.

What this does

A keyword density calculator finds the most frequent words and phrases in your text and their density as a percentage, with stop-word filtering and one-, two-, or three-word phrases.

How to use it

  1. Paste your text.
  2. Choose the phrase length.
  3. Toggle stop-word filtering.
  4. Read the density table.

How it works

For natural writing most individual keywords sit around 1–2%. Common stop words like the and of are ignored by default so the real topics stand out.

density = term count ÷ total terms × 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.
