About this tool
Counts how often your target phrase appears relative to total word count, checks whether it shows up in the first 100 words and the last paragraph, and surfaces the words that actually appear within five words of it — a quick, honest picture of how a page treats its topic. Density is a sanity check, not a ranking hack: search engines rank content on relevance and usefulness, so aim for the natural 1–2% range and treat anything above 4% as a sign to rewrite, not a dial to tune.
Analysis happens entirely in your browser with plain JavaScript — your article is never uploaded, stored, or tracked.
