What does this tool do?
The Keyword Density tool scans any text, counts how many times a specific word appears, and reports it as a percentage of the total word count. Content writers, bloggers and anyone curious about SEO can instantly spot whether a piece over-repeats a term.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
How it works
Paste your text and type the keyword you want to track. The tool lowercases the text, strips punctuation, and ignores any word shorter than the minimum length you set, so filler words like 'and' or 'the' do not skew the result. You see the count, density percentage and total words update live. It also ranks the 15 most frequent words as a bar chart you can click to switch keywords.
What is a healthy density
A common guideline is to keep a single keyword below roughly 1-2% of the text. Higher values can look unnatural to search engines and tire readers. Use the top-words list to see which terms truly dominate your writing; clicking any bar instantly makes that word the tracked keyword, so you can audit several candidates in seconds.
Frequently asked questions
What does minimum word length do?
It excludes words shorter than the number of letters you choose. Setting it to 3, for example, drops short words like 'is' or 'an' so the analysis focuses on meaningful terms.
How is the density percentage calculated?
The keyword's occurrence count is divided by the filtered total word count and multiplied by 100, shown with two decimal places.
Is keyword matching case sensitive?
No. Both your text and the keyword are converted to lowercase before counting, so 'Fox', 'fox' and 'FOX' all match the same term.
