Keyword Density Checker
Check that your main topic appears where it matters and spot words repeated so often the text reads unnaturally.
Inspect keyword usage on a page
Words are split with the language's own rules (including Chinese word segmentation), common words are skipped, and the top 1-, 2- and 3-word phrases are counted with their density and presence in the title, H1, description and URL.
Interpret the result
Make sure the main topic appears in the title, H1 and opening paragraph, add missing related terms naturally, and rewrite passages where one word dominates.
Prioritize fixes
Density is not a ranking factor and there is no target percentage; the tool counts words and cannot judge whether the text answers the searcher's question.
