The most effective and simplest method of earning money online is affiliate marketing. Being an affiliate means that you refer customers to a merchant, and get paid a percentage of what that customer spends. Since you are simply an affiliate and not the actual merchant you don't have to worry about taking care of the customers, shipping products, or any of the headaches of running a regular business, you simply collect your commission checks. Affiliate marketing is about connecting buyers and sellers, and rewarding those that facilitate the connections.
The most profitable market on the Internet is without a doubt, casino affiliate. The percentages offered by casino affiliate programs are much higher (30%-50%) than affiliate programs offered by regular online retailers (for example, K-mart offers 5%), and gamblers can spend much more than the average k-mart shopper. The average ranges for residual percentages per industry are listed below.
The real money-making potential of online casino affiliate programs doesn't come from the differences in percentages however, the real reason you can make a lot of money in the casino market is because the players you send to the casinos are yours for life. This means, if you direct a player to a casino, you will receive a percentage of what that player contributes, for the rest of your life. If the player you bring in stays with the casino for ten years, you'll likely be making money off of them for ten years.
