What is keyword density?

Keyword density is the percentage of times a keyword appears compared to the total word count. For SEO, 1-2% density per keyword is generally recommended.

Does it remove stop words?

How Keyword Density Analyzer works

This tool tokenizes your text, removes common English stop words (the, and, is, etc.), and counts the frequency of remaining words or n-grams. Keyword density is calculated as (keyword count / total word count × 100). The results are sorted by frequency and displayed with visual bar charts. N-gram analysis lets you see popular 2-word and 3-word phrases. Everything runs in your browser — your content is never sent to any server.
