What is a Keyword Density Checker?
A keyword density checker analyzes a piece of text and counts how often each word appears, then calculates the percentage that word represents compared to the total word count. This is a crucial tool for content writers and SEO professionals who want to avoid keyword stuffing or ensure a healthy balance of terms. By identifying the most frequent words, you can fine‑tune your content to match search intent without over‑optimizing. The tool runs entirely in your browser, so your drafts stay private.
How to Use
- Paste your text into the left panel — an article, a blog post, or any body of text you want to analyze.
- Check or uncheck the "Exclude common stop words" option. When enabled, words like "the", "is", or "and" are filtered out to give you a clearer picture of meaningful keywords.
- Click "Analyze" to see the word frequency table sorted by count. Each row shows the word, how many times it appears, and the density percentage. Use the copy button to export the report.
