What you need to do is sign up as an affiliate with other e-commerce sites. For example, Link Share
has hundreds of other companies looking for websites to send them customers. When one of these customers you sent buys a product
(or service), you'll receive a commission! The customer doesn't pay extra - but you make money! Commission rates vary a great deal.
Some companies pay 15% of the sale, others pay a fixed rate for each new customer, and other companies will pay both.
The first step is to sign up with referral program. Then select the companies or products you'd like to feature on your website,
and copy the HTML code to your website. From then on, the merchants you've selected will make the sale, collect the money, ship the
product, and pay you a commission. The only thing left to do is increase the traffic coming into your website.
I think
LinkShare is the best place to start. There are hundreds of merchants to choose from that
add quality to your site. But best of all, you earn cash for every sale you
refer.
