Keyword Density Checker - Analyze Keyword Frequency in Your Content

Use this free keyword density checker to analyze how often keywords appear in your content. Paste your article or page copy below to see word counts and density percentages for your top keywords, helping you avoid keyword stuffing and optimize for SEO.

How does the Keyword Density Checker work?

This tool splits your text into individual words, filters out common stop words (like "the", "and", "is"), and counts how often each remaining word appears. Density is calculated as (keyword count ÷ total word count) × 100, showing the top 20 keywords by frequency so you can check whether your content is naturally optimized or over-stuffed with a particular term.
