Keyword Density Checker

Before publishing a page, SEO specialists check which words and phrases dominate the copy: an unfocused text ranks for nothing, while an over-optimized one reads like spam. This keyword density checker gives you that picture live, as you type or paste.

The tool builds three tables — top single words, 2-word and 3-word phrases — each with the occurrence count and density as a percentage of total words. Multi-word tables matter most: people rarely search for one word, and repeated bigrams and trigrams reveal what your page is really about. A built-in English and Ukrainian stop-word filter hides glue words (phrases that start or end with one are skipped too), and you can switch it off to see the raw distribution. If you only need single-word frequencies without the SEO framing, this site also has a dedicated word frequency counter — this tool is about phrases and optimization.

Enter an optional target keyword and the checker reports its exact count, its density and whether it appears within the first 100 words — a common on-page recommendation. The often-quoted 0.5-2% range is shown honestly for what it is: a practical heuristic used by editors, not an official ranking threshold of any search engine. Write for readers first and use the numbers to catch accidental stuffing or a missing focus.

Everything runs locally in your browser: drafts, client pages and unpublished landing copy are never uploaded anywhere, and every keystroke updates all three tables and the target keyword summary instantly.
