If you run an Internet marketing web site and sell your own products or services, you probably follow up with your current customers using autoresponders and upsell them with products and services from related affiliate programs?

Note that if you don't do this, you are leaving money on the table.

Why? Simply, your customers have already spent money on your web site, and if they enjoy your product or service, they now trust you.

So, if you can endorse a high quality affiliate product or service to your current customers, they are more likely to buy it from you than from someone else who they don't know.

What Internet marketing affiliate programs should you join and endorse to your list in order to increase your online business profit?

The answer is - two-tier affiliate programs.

When you promote a 2-tier affiliate program, you earn commissions not only on your direct sales as in a regular affiliate program, but you also earn commissions on sales generated by people that you refer to the program.

Here is a list of proven, free-to-join Internet marketing two-tier affiliate programs:

Some of the above affiliate programs can even earn you lifetime commissions. It means that you don't just earn a commission on one sale, you can earn a commission on every subsequent purchase by your referrals.
