Analysis Density 1
Paste the copy and list the keywords to check; the tool computes density as occurrences divided by total words. Chinese is counted per character excluding whitespace, English per contiguous letter run, so mixed-language copy gets a consistent basis. Below 1% the theme is too faint, 1%–3% is the usual sweet spot, 3%–5% is getting dense and above 5% reads as keyword stuffing. Nothing leaves your browser.
