The article linked below by Linda Jenkinson shows you how to optimize a page without using keyword density tools.
The mistake many webmasters and keyword density tools make with keyword phrases is that you needn’t keep words in keyword phrases adjacent to each other.

Creative use of keyword phrases makes your content both more informative and a more enjoyable read for your visitors.
