What is keyword density?

Keyword density is the percentage of times a word appears relative to the total word count. For example, if "content" appears 5 times in a 500-word article, its density is 1.0%. Most SEO guides recommend keeping a primary keyword between 0.5% and 2.5%.

Does this tool send my text anywhere?

No. All analysis runs entirely in your browser using JavaScript. Your text never leaves your device and is not stored on any server.

Stop words are common function words — "the", "a", "is", "and", "of" — that usually carry no keyword value. The stop-word filter hides them so you can focus on meaningful content words.

Can I analyze multi-word phrases (bigrams)?

Yes. Switch the mode to "2-word phrases" or "3-word phrases" using the selector above the results table to see which phrases appear most often in your text.

How are percentages calculated?

Each word's density = (occurrence count / total word count) × 100. Total words are counted after the same normalization applied to the keyword table (lowercase, punctuation stripped).
