See What Your Text Actually Repeats

It's easy to lose track of how often a term repeats once you're deep in writing a page. This tool breaks your text down into single-word and multi-word phrase frequency, with density percentages and a direct warning if any term looks stuffed.

How to Use This Tool

  1. 1Paste your textAn article, product description, or any body of content.
  2. 2See word and phrase frequencySingle words plus 2-word and 3-word phrases, ranked by count.
  3. 3Check the density percentageHow often each word/phrase appears relative to total word count.
  4. 4Watch for stuffing warningsUnusually high density on any term is flagged directly.

Good to Know

  • Common stopwords (the, and, of, a...) are excluded from single-word results by default so the list actually reflects meaningful content, not just the most frequent words in any English text.
  • There's no single "correct" keyword density — search engines don't use a fixed target percentage — but a term appearing unnaturally often is still a useful signal that content may read as stuffed to a human reader.
  • 2-word and 3-word phrase frequency often surfaces more useful patterns than single words alone, especially for spotting repeated phrasing.
  • This tool works entirely on the text you paste — for checking a live page's actual on-page content, copy the visible text from the page first.

Frequently Asked Questions

Is there an ideal keyword density percentage?

No — search engines don't target a specific percentage, and chasing one can lead to unnatural-sounding writing. Use density as a rough signal for spotting overused terms, not a target to hit.

Why are common words like "the" and "and" excluded?

They're excluded from single-word frequency because they appear in almost any English text at high frequency regardless of topic, which would drown out the actually meaningful words.

Does this check a live URL or just pasted text?

Just pasted text — paste in the visible content from any page, document, or draft you want to analyze.
