https://agent-data-tools.revmesh2074.workers.dev/text/keyword-densityOverview
Keyword density of a text or a web page: the most frequent words and two-word phrases (English stop words removed), each with its count and share of all words, plus total and unique word counts. Give text, or a URL whose readable text is used (HTML, up to 1 MB). Use for SEO copy checks, comparing a page against a target keyword, or summarising what a page is about; for readability use text_stats.
