FAQ
What is keyword density?
Keyword density is how often a keyword appears in your text compared with the total word count. It is calculated as occurrences ÷ total words × 100%.
What is a good keyword density?
There is no fixed rule, but most SEOs keep a keyword under 2-3% of the total words. Use this tool to spot overuse (stuffing), not to hit an exact number.
Does it work with Chinese text?
Yes. Since Chinese has no spaces between words, Chinese text is analyzed in 2-character segments.
Is this keyword density checker free?
Yes, it is 100% free with no signup and no limits. All analysis runs locally in your browser.
