How to Use the Keyword Density Checker
- Paste your text and target phrase.
- Run the count.
- Review matches and token coverage alongside your editorial judgement.
Understanding Your Result
Density is a descriptive count, not a target or ranking score. Repeated keywords can make text less helpful.
Review the output before placing it in a document, publishing a file or using it in another application. Keep a copy of your original input so you can compare the result or try different settings. This interface is designed for a focused task: it does not replace a full editor, a professional assessment or the checks required by your destination service.
Working in Your Browser
The built-in Keyword Density Checker processes the data you enter in the current browser tab. Tool input is not submitted to a remote processing service. Clear the interface or close the tab when you finish, especially on a shared device. Downloaded files and copied text remain on your device until you remove them.
For another task, follow the related tool links below or return to all U18-CHAN tools. Related utilities can help you prepare an input or finish a result without installing extra software.
