How It Works

The Keyword Density Analyzer scans your text and counts how often each word appears. It calculates the density percentage for each keyword, which is the word's count divided by the total number of qualifying words, multiplied by 100.

Filtering options let you refine the analysis:

  • Min word length — Only includes words with at least this many characters (default 3), filtering out short words like "a", "to", "is".
  • Exclude stop words — Removes common English stop words (the, and, is, of, etc.) from the analysis, so you can focus on meaningful content keywords.

Keyword density analysis is essential for SEO content optimization. Search engines use keyword frequency to understand topic relevance. A density of 1-3% for primary keywords is generally recommended. Too low and search engines may not associate the page with the keyword; too high and it may be flagged as keyword stuffing.
