Keyword Density Checker
Analyze keyword frequency and density in your text. Free keyword density checker for SEO — find top words and phrases.
Three steps to get started
Paste your content
Type or paste any text — blog post, article, product description, or landing page copy.
Adjust the filter
Set the minimum word length to 3, 4, or 5 characters to focus on meaningful keywords.
Review keyword usage
Check the top 20 keywords by frequency and density. Optimize for natural, balanced keyword usage.
Understand how your keywords are distributed
Keyword density analysis gives you a clear picture of which words dominate your content. For SEO writers, this helps ensure primary keywords appear often enough to be relevant, but not so often they trigger over-optimization penalties. For editors, it reveals unintentional repetition that may weaken prose quality.
For SEO content: Use this tool to verify that your target keyword and its semantic variants appear at appropriate frequencies. Google rewards content that covers a topic comprehensively — not content that repeats one phrase obsessively.
For writers and editors: High frequency of a single word often signals a readability problem. If "process" appears 15 times in a 500-word article, readers will notice. This tool makes those patterns immediately visible.
Minimum word length filter: The 3-character default includes most meaningful words while excluding two-letter prepositions and articles. Switch to 4 or 5 characters to see only substantive content words and ignore function words entirely.
The top 20 results are shown in frequency order, with a visual bar showing relative frequency. The top result is always shown at full bar width; all others are shown proportionally. All analysis is instant and happens entirely in your browser.
