What is keyword density, and why does it matter?
Keyword density is the percentage of times a keyword appears compared to the total number of words in your text. For example, if “content marketing” appears 5 times in a 500-word article, its density is about 1%. It’s a quick way to check whether you’re using a topic’s main terms enough to be relevant — without overdoing it.
There is no magic number, but modern SEO rewards natural writing. If a keyword’s density is very high (roughly 3% or more), it can read as “keyword stuffing,” which hurts readability and can be flagged by search engines. Use this checker to keep your main keywords present but comfortable, and always write for people first.
