What does the keyword density tool count?
Word frequency, ranking and density percentage per word, with frequent words highlighted — checking whether keyword distribution is reasonable.
What density is ideal?
Typically 2%-5%: too low misses search queries, too high risks keyword-stuffing penalties. Adjust by article length.
Can stop words be excluded?
Yes — toggle "exclude common words" to filter "the, a, and, of" so analysis focuses on real keywords.
Is online analysis safe?
Safe. Statistics run locally; text never uploads, suitable for unpublished drafts.
What is it best for?
SEO writing, content optimization, competitor copy analysis, title keyword testing and content strategy.
Are there limits on free use?
No. Free, no registration, long-text analysis supported.
Does it support Chinese?
Yes — accurate frequency counting for both languages, with Chinese segmented properly.
How is density computed?
Occurrences ÷ total words × 100%, shown as bars for easy comparison.
