What is Keyword Density?
Keyword density measures how often a term appears relative to total word count. Most SEO experts recommend 1-3% for primary keywords.
How it works
We tokenize the text into words, count occurrences of each keyword (case-insensitive), and compute density = occurrences / total words x 100.
