How to use
Paste or type your text into the box above, then read or copy the result. Everything runs privately in your browser, your text is never uploaded to a server.
How to use this tool
- Paste or type your text into the input box.
- Click the check or analyze button to scan the text.
- Review the most frequent words and their density percentages.
- Use the results to spot repeated keywords or confirm the text stays on topic.
Step by step, what happens
- The tool reads the full text you provide and splits it into individual words.
- It counts how often each word appears, usually ignoring differences in capitalization.
- It compares each word count against the total text length to calculate density percentage.
- It lists the words from most frequent to least frequent so you can quickly spot repetition.
- You can use the output to check whether one word is dominating the text more than it should.
Worked example
A writer wants to check whether a short product description repeats the same keyword too often.
Input: blue shoes are lightweight shoes for everyday wear
- The tool scans the sentence and finds the repeated word shoes.
- It counts shoes twice, while the other words appear once each.
- It shows shoes as the most frequent word with the highest density in the text.
- It lists the other words with lower density so the repetition is easy to compare.
Output: shoes: 2, 28.57%
blue: 1, 14.29%
are: 1, 14.29%
lightweight: 1, 14.29%
for: 1, 14.29%
everyday: 1, 14.29%
wear: 1, 14.29%
Tips and common mistakes
- Remove navigation text, headers, or repeated boilerplate before checking density, since those words can distort the results.
- Do not rely on one repeated term alone. A healthy page usually has related words and phrases, not the same keyword over and over.
- Check for close variants too, such as singular and plural forms, because they may still signal overuse even if they are counted separately.
- Use the tool on the final draft, not an early outline, so the density numbers reflect the text readers will actually see.
Frequently asked questions
What is keyword density?
Keyword density is how often a word appears as a percentage of total words. It signals what a page is about.
What is a good density?
There is no fixed ideal, but 1-2% per target keyword is typical; much higher can look like keyword stuffing.
Are stop words ignored?
Yes, common words like "the" and "and" are excluded so the meaningful keywords stand out.
