What is a good ratio of money-posts and non-money posts to have on your site? For example, if you have a site about balls and you see that "red balls", "blue balls", and "orange balls" will all give you a lot of traffic and a lot of money, because they have low competition and high adsense potential, how many posts on your site should target those keywords and how many should be just informative posts with no targeted keyword? What do you think? I don't think that you can just make every post target a keyword, that will be way too spammy looking for Google.
