If you have set up Google AdSense correctly and you have an approved AdSense account then there's nothing else that you need to do. Your ads should now be shown 60% of the time around your hubs. You should sign up for Google Analytics as well so you have proper statistics about visitors.
You can choose to create segments within your google adsense account to optimize the types of ads that are displaying. This requires some A/B testing though.
I understand that Adsense will use smart pricing to change the payout ratio on their side if you have too many non-performing sites (with volume). It is probably worth doing some house cleaning from time to time to make sure there are no clangers attached to your account that may be pulling it down! I think other folk have covered this in more depth though.
Happy hubbing.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
