Let's say I have a standard issue web page with 500 - 600 words and I'm priming my page for two specific keywords (for the purposes of this example). We know that these words need to feature within the context of the page but how many times should they be used in the body text? How many times is too many? How few is too little? Does it even make any difference any more? Conventionally I have learned and used 2 to 7 % density and typically I've seen SEO organisations use roughly 4 % density for two word phrases.
If I want this page to perform well in the search engines what are the best practises in relation to densities? What strategies have worked for you on real world projects?
