Frequently asked questions


What does the keyword density tool show?
It shows how often each word and phrase appears in your text, expressed both as a count and as a percentage of total words.


What keyword density percentage should I aim for?
There is no official optimal density. Avoid obvious over-repetition (above 3-4% for a single keyword). Natural writing that covers a topic thoroughly typically produces appropriate density without forcing it.


Does Google penalize keyword stuffing?
Yes. Unnatural repetition of keywords, especially at the expense of readability, is a known negative signal. Write for readers first. Include keywords where they fit naturally.


Can I check for specific phrases?
Yes. The tool analyzes both single words and multi-word phrases.


Does it work offline?
Yes.


Should I include stop words in my analysis?
Stop words like the, and, or are excluded from analysis by default because they add no SEO value. Enable stop words if you need a complete frequency count for other purposes.
