I have read PHPBUILD guide about autority sites and I realized that my main keyword phrase is about 0.9% - density, which is good according to his guide. But theres a single words that over 3% in the text. For instance: my main keyword is "shoes for little feet" in 0.9% density which is good. But the word "little feet" got in 3% Density and the word "Shoes" is in 3.05% density. This should be reduced ? Because I saw alot of website in this situation. So a single / 2 phrase word will couse a over optimiztion to my website ? **I checked the keyword density with SEO BOOK keyword density tool** Thank u guys.
