Affiliates are sellers who sell a product someone else created for a commission. If you have some basic Web skills and are comfortable with marketing and promoting products online, consider signing up for an affiliate program and jump right in. If you already have a blog or Website, consider selling items on Amazon.com through their affiliate program. Also, take a look at Commission Junction, one of the leading affiliate sites on the Web. Youâ€™ll need to provide some basic information about an existing Website and can qualify for different types of products.
