Keyword Density Checker

The Keyword Density Checker scans your draft and reports how often every word — and every two- and three-word phrase — appears, with counts and percentages. It helps you catch accidental keyword stuffing, confirm that your main topic actually dominates the page, and notice phrases you repeat without realizing. It is an honest mirror for a draft, not a ranking promise.

How to use Keyword Density Checker

  1. Paste your article or page copy into the box.
  2. Read the three lists: single words, two-word phrases and three-word phrases, sorted by frequency.
  3. Adjust your draft if one phrase is crowding everything else out, then re-check.

Supported behavior

  • Text is compared in lowercase with punctuation stripped, so 'Cats,' and 'cats' count together.
  • Percentages for one-word phrases use the total word count; phrase percentages use the total number of phrases of that length.
  • Use the Show option to cap each list at the top 10, 25 or every phrase.

Best for

  • Reviewing SEO drafts for accidental over-optimization.
  • Checking that a product page actually focuses on its topic.
  • Editing out phrases you repeat unconsciously.

Limits

  • There is no magic density number that guarantees rankings — treat very high percentages as a readability warning, not a target.
  • The checker counts exact matches only; synonyms and related terms are listed separately, not merged.

Privacy notes

  • Everything runs on your device: the text you type never leaves your browser.
  • Your draft is analyzed in the browser and never uploaded, which matters for unpublished work.

Keyword Density Checker FAQ

What keyword density is ideal?

There is no proven ideal. As a readability rule of thumb, a single phrase above roughly 3–4% of total words usually means the text repeats itself; natural writing rarely needs a target at all.

Why check 2- and 3-word phrases?

Because stuffing hides in phrases. A page can look fine word-by-word while one three-word phrase repeats twenty times. Phrase lists surface that.

Does it ignore common words like 'the'?

No — every word is counted, because hiding them would also hide real patterns. Function words naturally top the one-word list; the phrase lists are where the insight is.
