Common questions about the free online keyword density checker.

It is the share of the text made up of a word or phrase, usually written as a percentage of the total words.

Most pages read naturally between 0.5 and 2.5 percent, and above roughly 3.5 percent a page can look over-optimised.

There is no ideal figure. Write for readers, cover the topic fully and let the density fall where it falls.

Every overlapping group of two or three neighbouring words is counted, so a phrase is scored wherever it appears.

Yes. Switch the input mode to meta tag, paste the tag, and the content attribute is read for the analysis.

It means a phrase appears so often that the page reads as written for crawlers rather than for people.

None. Every word of two characters or more is counted, so short function words still appear in the lists.

Modern ranking systems work from meaning rather than counts, but extreme repetition can still look like spam.
