what is the ideal range of keyword density?

[JoeAmadon]

I think the idea of optimal keyword density is a bit out-of-date, but I believe, historically, Google preferred 4-6%, while Yahoo and MSN liked a 6-9% range. These days natural writing is the best way to go as search engines have gotten much better at identifying unnatural writing patterns and factoring in the words that are typically associated and are expected to be seen in good writing about a topic/keyword.

See this post from Rand that has a section on Keyword Density. Short version is that it doesn't make sense to look at a specific percentage, but make sure that you at least use your keyword on your page, it's readable, and you don't stuff the page. http://www.seomoz.org/blog/some-opinions-on-the-seo-myths-realities-fight
