FAQ
Common questions about the Keyword Density Checker tool.
What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears in a piece of content relative to the total word count. It helps SEO professionals gauge keyword usage.
What is a good keyword density?
Most SEO experts recommend a keyword density between 0.5% and 2.5%. Going well above 3-5% may trigger over-optimization warnings and could be seen as keyword stuffing by search engines.
Does the tool handle stop words?
Yes. Common stop words such as 'the', 'and', 'of' and 'to' are excluded by default so the frequency tables focus on meaningful keywords, but you can include them if you want.
