The jury appears to still be out on keyword density. Historically, more keywords on a page tended to show up higher in search results, but abuse of keyword repetition has changed how search engines treat this. Jason Glover’s article, “What is the Ideal Keyword Density?” cites that “no more than 5% keyword density is recommended by Google” and stresses the same point we do: quality content is crucial. If it doesn’t make sense, it is not going to work for your users anyway. Write for humans, not for machines.
