About Keyword Density Checker

Which words and phrases does this page actually repeat? Paste the text and it counts every phrase up to five words long, reports how much of the page each one occupies, and ranks them — which is often not the phrase the page was written to rank for.

Stop words are ignored by default, and a phrase that begins or ends on one is treated as a fragment rather than a keyword, so of the standing desk does not crowd out standing desk. Give a target phrase and it says how much of the page that phrase is, and where a natural weight sits.

Density is a diagnostic, not a target. No search engine has ranked on keyword density for well over a decade; what the number is good for is spotting the two failure modes — a page that never says what it is about, and a page that says it so often it reads like a machine wrote it.

The graded block scores the text rather than the page: stuffing a phrase past 5%, a target phrase that never appears, and a page too short to measure each take their share off it.

Where it helps

  • Counts phrases of one to five words, not just single words, which is how people actually search.
  • Ignores stop words and fragments, so the ranking is of topics rather than grammar.
  • Flags stuffing above about 5% and thin content below 300 words.
  • Reports the reading time and the total, so the density figures have context.
  • Local, so unpublished copy stays on the machine.

Limits

  • Density is not a ranking factor: treat a number as a symptom, never as a target to hit.
  • It counts the text you paste, so navigation, headings and alt text are included or excluded depending on what you copy.
  • It has no notion of synonyms or related terms, which is how search engines have understood topics for years.
  • Short texts produce wild percentages — one extra mention in 100 words moves the figure by a point.

Frequently asked questions

What density should I aim for?

None. If pressed: a phrase that is the topic of a page usually lands between 0.5% and 2.5% without anyone trying. Above 5% reads as stuffing to a person, which is the real problem.

Why is my target phrase missing from the table?

Because it appears fewer than twice, or it begins or ends on a stop word. If it is genuinely the topic, it belongs in the title, a heading and the opening paragraph.

Does keyword stuffing still get penalised?

Yes — it is named in Google's spam policies. More often it simply reads badly, and people leave.

Should I count headings and alt text?

Include the text a reader sees, which is headings and body copy. Alt text serves a different purpose and skews the counts.
