Frequently Asked Questions
What is keyword density?
Keyword density is the percentage a word appears relative to total words. A 2% density means the word appears 2 times per 100 words. There is no perfect density — focus on natural writing.
Why exclude stop words?
Common words like "the", "a", and "is" dominate any text and hide meaningful keywords. Excluding them surfaces the words that actually matter for SEO and content analysis.
What is a good keyword density?
There is no fixed target. Most SEO guidance suggests a primary keyword appears naturally a handful of times. Stuffing keywords to raise density can hurt rankings.
Is my text sent anywhere?
No. Analysis happens entirely in your browser. Your text never leaves your device.
