Use this free keyword density checker to instantly analyze any text — paste your article, blog post, or product description and see the top single keywords plus 2- and 3-word phrases ranked by frequency and density, helping you write SEO-optimized content that ranks without over-optimizing.

Multi-word phrases (also called n-grams) reveal semantic clusters in your text. They help you spot long-tail keyword opportunities, check whether your target phrases are used with the right frequency, and see if related terms naturally group together the way readers and search engines expect.
No. Keyword density is one small signal among hundreds. Modern search engines weigh topical relevance, content depth, user engagement, backlinks, and page experience far more heavily. Use this tool to avoid obvious over-optimization or under-optimization, but focus primarily on writing clear, helpful content.
