Keyword density is the number of times a word appears in your text divided by the total word count. Paste an article here and this checker breaks it into single keywords, two word phrases and three word phrases, showing the count and the density percentage for each. It also reports total words and unique words, so you can see how varied the writing actually is. Nothing is uploaded; the counting happens in your browser.
There is no exact density target that ranks a page, but there is a range that reads naturally. Most well written pages sit between 0.5% and 2.5% for their main keyword, and anything above 4% usually means the phrase is being repeated past the point of sounding human. This tool flags those cases in red. Use the stop word filter to hide words like the, and, of, and raise the minimum word length when short words crowd the results.
How to use the Keyword Density Checker
- Paste your article, landing page copy or product description into the text box.
- Set the minimum word length and choose whether to exclude common stop words such as the, and, of.
- Pick how many results you want per table: top 10, 20 or 50.
- Press Check Keyword Density and read the three tables, watching for any keyword marked in red above 4%.
Frequently asked questions
What is a good keyword density?
There is no official number. Pages that read naturally usually land between 0.5% and 2.5% for the main keyword. Treat density as a readability check rather than a ranking dial. If a phrase is above 4%, read the text aloud and you will normally hear the repetition.
Does Google still use keyword density as a ranking factor?
Not as a direct factor. Google matches pages on meaning and context rather than counting repetitions, and keyword stuffing is explicitly against its spam policies. Density remains useful as a diagnostic: it shows when a page repeats one phrase far more than a human writer would.
Why do two and three word phrases only show when they repeat?
In any normal article most phrase pairs appear exactly once, which would fill the table with noise. Phrases are listed only when they occur two or more times, so what you see are the combinations you actually repeat across the page.
What do the stop word and minimum length options do?
Stop words are common English words such as the, is, and, of that carry no topical meaning. Excluding them removes them from the single word table and drops phrases that start or end with one. Minimum word length hides short tokens so the results focus on real keywords.
