ok, first you need to decide which niche you want to enter, i.e what is/are your target markets? Internet marketing, games, shopping, health, golf, fishing, or ????
you need to decide first. then you can look for affiliate programs for your market.
e.g. ebooks or software, you can register an account on click back, it's free
or you want to sell some phyical stuff, then you can register on cj.com, clixgalore.com
, shareASale.com, linkshare.com etc.
or for books, you can go to amazon and create an associate account (but they don't pay good on amazon only 20% on commission or something, but for click bacnk you can earn up to 50% or more! )
