Keyword Density Checker — FAQ
Paste your text and the tool lists each word with how many times it appears and its density percentage. Everything runs in your browser, so your text never leaves your device.
Density is the number of times a word appears divided by the total word count, shown as a percentage. A word used 10 times in a 500-word text has a density of 2%.
There is no fixed target, and search engines do not publish one. The checker shows your numbers so you can spot accidental repetition or a missing main term, not to chase a magic percentage.
The checker counts single words by frequency. For phrases, check the individual words and read the text to judge whether the phrase itself is overused.
It is handy for bloggers and writers reviewing an article before publishing, to catch a term repeated too often or a topic word that barely appears.
Common words appear in the frequency list too, since they are part of the text. Focus on the content words when judging whether a topic term is overused.
Yes. Paste the whole article at once and the tool counts it in one pass.
No. The tool is free to use with no account or signup required.
No. Everything runs in your browser and no text is uploaded anywhere.
No installation is needed. The tool runs entirely in your web browser and is completely free.
