Keyword density is the rate of times a catchphrase or expression shows up on a site page contrasted with the aggregate number of words on the page.

Many SEO experts consider the optimum keyword density to be 1% to 3% percent and Google documentation states that your keyword density for any keyword or phrase should be less than 5%. You must make your own decisions about what is right for you but it seems like a keyword density of around 2%-3% is just right.
