Tokens = letters, digits, underscore, Cyrillic; case-insensitive. Phrases = consecutive tokens, non-overlapping matches. Hyphens split words (same as word frequency).

When live keyword density wins

You are polishing blog posts, product pages, or newsletter copy and need a quick read on how often a focus term appears versus total length. The hero shows density %; secondary tiles show matches, tokens, and read time—computed locally.

How it works

  1. Paste or type in the left column.
  2. Enter a focus keyword or short phrase—the indigo Live density panel updates automatically.
  3. Read What this means / Next, then Copy density report for clients or your notes.

What each metric means

  • Density % — matches ÷ total word tokens in your paste.
  • Matches — how many times the keyword or non-overlapping phrase appears.
  • Total tokens — word-like pieces after normalization (hyphens usually split).
  • Read time — rough minutes at ~200 wpm on your paste.
  • Top token in paste — the most frequent token overall (context for repetition).

Privacy: Keyword density is designed to run locally in your browser. We do not store your paste on our servers.

FAQ

  • Is anything uploaded? No—math and copy stay in this tab.
  • Does this match Google’s index? No—search engines use their own parsing; this is an editor’s quick check on your paste.
  • What is a “good” density? There is no universal target—aim for natural language; use the verdict as a sanity check.
  • Why zero matches? Spelling, plurals, or hyphenation can differ from your focus field—try a shorter root token.
  • What does Copy density report include? Header lines with focus term, %, matches, tokens, optional read time and top token.
  • Mobile? Yes—the panel stacks and stays readable on narrow screens.
