Keyword density checker

Which words and phrases does your text actually repeat?

Keyword density is a phrase's share of the total words in a text. Paste yours below to rank single words and 2- and 3-word phrases by count and density — useful for spotting accidental stuffing, checking that a page really is about what its title claims, and catching a term you have repeated forty times without noticing.

How density is calculated

For single words: density = (times the word appears ÷ total words) × 100. For phrases, the numerator is the phrase count and the denominator is the number of phrases of that length in the text. Word matching is case-insensitive, and an apostrophe inside a word (don't) keeps it as one token. With stopword removal on, single words are ranked after dropping a standard list of English function words (the, of, and…) — otherwise the top of almost every ranking is the same handful of glue words, which tells you nothing.

What density should you aim for?

There is no magic percentage, and any tool that promises one is selling something. Search engines rank pages on far more than repetition. Used honestly, density is a diagnostic: a main topic that never reaches roughly 0.5% may be under-explained; a phrase pushed past 2–3% usually reads as stuffed and is worth rewriting for a human. Check the phrases too — writers often repeat a 3-word phrase verbatim far more than they realise.

Frequently asked questions

Why is "the" not at the top of my ranking?

Because stopword removal is on by default for single words. Switch it off in the controls to see the raw ranking, glue words included.

Does the checker count plurals and variants together?

No — garden and gardens are counted separately, and so are verb forms. That is the honest count; merging variants would be a guess dressed as a statistic.

Is my text uploaded for analysis?

No. The analysis runs in your browser, like every tool on this site.
