FAQ
Common questions.
What is keyword density?
Keyword density is the percentage of times a keyword appears relative to the total word count in your content. For example, if a keyword appears 5 times in a 500-word article, its density is 1%.
What's a good keyword density for SEO?
Generally 1–2% is recommended, though it varies by content type and search engine guidelines. Keyword stuffing — overusing keywords beyond natural usage — can harm your rankings.
Does this analyze single words and phrases?
Yes, it shows individual keywords along with their count and density percentage, filtering out common stop words so you see only meaningful terms.
Is there a content length limit?
No, paste articles or content of any length. The tool runs entirely in your browser, so performance depends on your device rather than a server limit.
