How is keyword density calculated?

The number of times a word or phrase occurs is divided by the total number of words in the text and shown as a percentage. The same formula is used for phrases of two and three words.

What keyword density should I aim for?

There is no figure that search engines reward. A target keyword at roughly 0.5% to 2.5% usually reads naturally; far above that, text starts to look stuffed. Treat the range as a readability check, not a ranking rule.

Can I paste HTML instead of plain text?

Yes. With "Remove HTML tags" on, tags, comments, scripts and styles are dropped and common entities are decoded, so only the visible text is counted.

Density is occurrences divided by the total word count. A target keyword between 0.5% and 2.5% usually reads naturally; search engines do not reward a specific figure.

Paste an article, a product page or its HTML source and see which words and two- and three-word phrases carry the text. Density is the number of occurrences divided by the total word count. Set a target keyword to see its count and density and whether it sits in the 0.5% to 2.5% range that usually reads as natural. Stop words can be ignored, short words filtered out and HTML tags, scripts and styles removed before counting. The ranking can be copied or downloaded as CSV. Your text is analysed in the browser and is never uploaded.
