Keyword density is the percentage of times a word or phrase appears relative to the total word count of your content. It is a quick diagnostic: very high density can read as keyword stuffing, while a target term that barely appears may signal thin topical coverage.

Paste your draft and this tool counts single words and multi-word phrases, ranks them by frequency, and shows the density of each so you can write naturally for readers first.

How to analyze your content

  1. Paste or type the article you want to check into the text box.
  2. Read the total word count and the ranked list of top terms.
  3. Switch between single words, two-word and three-word phrases to see how your topic clusters.
  4. Adjust your draft if any single term is overrepresented, then re-check.

How to read the numbers

Density What it usually means Suggested action
Under 0.5% Term barely covered Add depth if it is your main topic
0.5% – 2.5% Healthy, natural range Leave as is
2.5% – 4% Getting repetitive Vary wording, add synonyms
Over 4% Risk of keyword stuffing Rewrite to read naturally

These bands are rules of thumb, not algorithm rules. Modern search engines reward relevance and readability over exact ratios.

What the report includes

  • Total words, unique words and reading-level friendly counts.
  • Frequency and density for single words and 2–3 word phrases.
  • Automatic removal of common stop words so the list stays meaningful.
  • Instant recalculation as you edit — everything runs locally.

Frequently asked questions

Is there an ideal keyword density?
There is no magic number. Aim to cover your topic thoroughly and mention your main term naturally; anywhere from roughly 0.5% to 2.5% is typical for well-written content.
What are stop words?
Common words like “the”, “and” and “of” that carry little topical meaning. We exclude them so the ranking reflects your real subject matter.
Can high density hurt rankings?
Stuffing a keyword to inflate density can read as spam and undermine the page. Write for people and density usually takes care of itself.
