Set up Adsense : use for Google Adsense program
Adsense for Feed : it will embed a ads for your feed but not work too much.
Amazon Associates : make money with Amazon, if your have family with Google Adsense and similar program, you can try this, but if you do not know too much, I recommend you not try now. You may spend a year without get payment from Amazon. When you have a lot of traffic about 1000 visitors per day with most from US, you can try them.
