Set up a website. Professional or business websites can also use the Affiliate program. However, they are best used with people who do not sell similar products on their website, since Amazon's marketplace can drive business away. If you have a website promoting different products, a club, a non-profit or a service, then you can recommend quality products on your site and make money doing it.
Many affiliates struggle to make enough profit from the sales they make to allow them to reinvest that money into more content or marketing. Once you do find a product that people can and will buy online, make sure it offers enough commission per sale to make it worth your while. There’s little sense in promoting light bulbs for 1% profit per sale.
You should also make sure you aren't competing with your own affiliates for eyeballs. Any marketing channels you're using, such as search engines, content sites or e-mail lists, should be off limits to your affiliates. Put marketing restrictions into your affiliate agreement and notify partners immediately. It's your program--you set the rules. Or, if you prefer, you can let your affiliates run the majority of your internet marketing.
