About the Keyword Density Checker
Density is a diagnostic, not a target. There is no percentage that makes a page rank, and chasing one produces text that reads like it was written for a machine. What the number is genuinely good for is spotting two failures: a page that never states its own subject in plain words, and a page that repeats one phrase so often that a human would notice.
The tool counts single words, two-word phrases and three-word phrases separately, after stripping navigation boilerplate and stop words. Three-word phrases are usually the most revealing, because they show the actual topic rather than the vocabulary.
A common pattern worth checking for: the target phrase appears in the title and nowhere in the body. That page is describing something the text never covers, and no amount of link building will fix it. The other pattern is a page whose top phrase is your own brand name — which means the content is about you rather than about what the reader searched for.
Common questions
Is there an ideal keyword density percentage?
No — this was a common claim in the 2000s and Google has never confirmed a target ratio. Use the number to catch two failures: a page that never states its topic, or one that repeats a phrase unnaturally often.
Why do three-word phrases matter more than single words?
Single words are often too generic to be useful ("seo", "tool") while three-word phrases usually reveal the actual subject of the page, closer to how people phrase real searches.
Does high density trigger a penalty?
There's no specific 'keyword stuffing' percentage threshold in Google's algorithm, but text that reads unnaturally to a person is exactly the pattern Google's helpful-content systems are built to demote.
