- Enter or paste the source data and keep an untouched copy when the order or formatting matters.
- Choose the available options, then select Process.
- Review the entire result before copying, downloading, publishing or importing it elsewhere.

Before you use the output
The analysis lowercases words, excludes short words and a list of common English stop words, and reports the fifty most frequent remaining terms. The percentage uses those filtered words, not every word in the original text. There is no target percentage that establishes a search ranking. Treat repeated terms as an editing prompt and read the paragraph in context.

Limits and accuracy
Density is not a ranking score and should never replace natural, useful writing. Keep the original text, verify important results and use a specialized application when a task carries legal, security, financial or production risk.
Privacy and safety
This tool is intended for ordinary text and development samples. Do not paste passwords, authentication tokens, private keys, payment information, medical records or confidential client data into a general-purpose web page. Closing or refreshing the page can remove unsaved input.
Frequently asked questions
Does Keyword Density Checker upload my text?
No. The tool is designed to process input in your browser. Avoid pasting passwords, private keys or highly sensitive records into any ordinary web tool.
Can I use the result commercially?
You can use the transformed text in your own work, but you remain responsible for checking accuracy, rights, formatting and any platform-specific requirements.
Why can the result differ from another application?
Density is not a ranking score and should never replace natural, useful writing. Different applications can use different parsing, language and encoding rules.
