What is the Keyword Density Checker?
Analyze keyword frequency and density percentage to optimize content without over-stuffing.
The Keyword Density Checker scans your content and ranks every word by frequency, showing exact counts and percentage density. It filters out short words (under 3 characters) to focus on meaningful keywords. Use it to ensure your target keyword appears at the right density (1-2%) and to spot unintentional keyword stuffing that could trigger search engine penalties.

Key Benefits
Avoid Penalties
Catch keyword stuffing before it triggers algorithmic penalties.
Optimize Naturally
Achieve ideal 1-2% density for primary keywords.
Discover Themes
See which topics your content naturally emphasizes.
Competitive Analysis
Paste competitor content to reverse-engineer their keyword strategy.
How to Use This Tool
Paste your article or blog post content into the text area
Review the top 20 most frequent words with counts and percentages
Check if your target keyword appears at 1-2% density
Identify overused filler words that dilute topic relevance
Adjust content and re-check until density is optimized
Common Use Cases
- SEO writers checking target keyword density before publishing
- Content auditors reviewing existing pages for optimization opportunities
- Competitors analysis - paste rival content to find their keyword focus
- Editors ensuring editorial guidelines for keyword usage are met
- E-commerce teams optimizing product descriptions for search
Pro Tips
- Primary keyword density of 1-2% is ideal; above 3% risks over-optimization
- Check density for LSI/related keywords too - not just your primary term
- Run the checker on top-ranking competitor pages to benchmark density
- Density alone doesn't guarantee rankings - focus on search intent and quality
