Wouldn't it be nice if Google just published their formula? The people who know this formula must get a good laugh out of how much energy we put into these discussions.
There is no good keyword density, so long as you use the keyphrase at least once that's all you need. Overuse of the keyword could be bad though. Someone for Google comfirmed this not long ago.
I would go for 5 - 7% of keyword density. I would build a lot of backlinks to that page also, one of your competitors for that keyword is entrepreneur.com, and they pull high ranking. Link out to a few authority sites too, and get some articles out there pointing back to your page. Good luck, Carmen
5-7% is good, though the good density value tends to be lower for large, content-full pages. However, please do not focus on the values, focus on the content. Simply write your copy as usual, for people like you and me. This is the best tactic.
according to me ..Keyword Density follows below meaning The density formula is D = WC/KC (D = density; WC = word count; KC = keyword count) For major keywords target 3-7% density For minor keywords target 1-2% density Keyword density measures how relevant keywords are in a page. The formula density = word count divided by keyword count will provide a general idea of the density percentage. For major keywords try to keep the density between three and seven percent. For minor keywords keep density between one and two percent. Try to optimize between five to ten keywords per web page. Avoid the unethical practice of keyword stuffing. You will be penalized and possibly banned from the search engines which is worse than doing no optimization at all. Keyword stuffing uses various techniques but it is basically stuffing a page and/or meta tag with several occurrences of a keyword or keyphrase.
"Keyword density is, without question, NOT a part of modern web search engine ranking algorithms for the simple reason that it provides far worse results than many other, more advanced methods of keyword analysis." - http://www.seomoz.org/blog/rewriting-the-beginners-guide-part-4-continued-keyword-usage
