Affiliate marketing has gone beyond selling products to people before you get your commission. There are programs that pay you for just sign ups that you referred to their site. With this you can make lots of money online. The program an going to talk about is crewdle. Crewdle pays it's partner's $1 for each successful referral they get. Just imagine referring 20 people in a day that means you'll earn $20 which is equivalent to 4,000 naira depending on the present dollar to naira rate now.
