Keyword Density Checker
See which words and phrases your copy actually repeats, how often, and what share of the text they take up — counted in your browser, with no target percentage to chase.

What this tool does
Paste your copy and this tool counts every word and phrase in it, then reports what share of the text each one takes up. Density is the count of a phrase divided by the total word count — a phrase appearing four times in a thousand words is 0.4%. You can also name a target phrase and see its count on its own.
The important caveat is that density is a diagnostic, not a target. Google has said for years that keyword density is not a ranking factor, and the percentages people quote — 1%, 2%, 3% — come from studies of pages that already ranked rather than from anything a search engine measures. What this tool is genuinely good for is catching repetition you did not notice: the same adjective four times in one section, or a phrase you used in every paragraph without meaning to.
How to use it
- Paste the text you want to check. The table fills in as you type.
- Type a target keyword if you have one. Its exact-phrase count and density appear in the tiles, whether or not it makes the top of the table.
- Switch the phrase length between one, two and three words. Two- and three-word phrases are usually the useful view: single words are dominated by whatever noun the topic forces you to repeat.
- Read the table for things you did not intend — a word repeated in every paragraph, a phrase used four times in one section — rather than for a percentage to hit.
Common use cases
-
Editing a first draft
The most common finding is not stuffing but accidental repetition: the same transition word opening four paragraphs, or a product name eleven times on one screen.
-
Checking competitor copy
Paste a page that outranks you and see which phrases it repeats. You are looking for the vocabulary of the topic, not a density figure to copy.
-
Auditing AI-assisted drafts
Generated text tends to circle the same few words. The table shows that pattern in seconds, before a reader notices it halfway down the page.
-
Confirming a rewrite helped
Run the before and after versions and compare the table. If the words you were trying to reduce are still at the top, the rewrite moved sentences around without changing the vocabulary.
Frequently asked questions
What is a good keyword density?
There is no good number. Google has said repeatedly that keyword density is not a ranking factor, and no threshold triggers a filter or a penalty. The 1% and 2% figures that circulate come from correlation studies of pages that already ranked, which is not the same as a cause. Treat density as a way to notice repetition, never as a target to write towards.
How is density calculated here?
The number of times the phrase appears, divided by the total word count, as a percentage. A three-word phrase counts once per occurrence rather than three times, so a phrase appearing four times in a 1,000-word article is 0.4%. That is the convention most tools use, which is why the figures are comparable between them — and why they all share the same weakness, that a percentage says nothing about whether the repetition reads naturally.
Should I rewrite text that repeats a word too often?
Only when the repetition reads badly to a person. Repeating a term is how a reader knows what a page is about, and search engines have matched synonyms for years, so swapping in a thesaurus word buys nothing and often reads worse. Cut repetition when it makes the prose clumsy; leave it alone when it does not. The table is there to show you the pattern, not to tell you it is wrong.
