Make real money from affiliate programs

As oftenly quoted, about 90% of affiliates make no money from affiliate programs. The top 10% makes all the money.

What should be the reason for these big difference between those who succeed and those who fail?

Here are my tips when choosing affiliate programs:

1. Only promote products/services in a niche that is in demand and profitable.
2. Join in programs where you can earn at least 20% of commissions on sales.
3. Only promote products that are related to your website.
4. Concentrate on promoting a product/programs that pay recurring or lifetime commissions. Meaning , make a sale once and get paid indefinitely for any repeat sales to the same customer.

This is the big secret of the super affiliates.
