I’ve read a lot of horror stories where Amazon has randomly closed people’s accounts for different reasons. Fair enough – many of these are due to breaches of their terms and conditions (e.g. failing to properly disclose links, not using the appropriate images and links provided in the affiliate dashboard, buying from one’s own affiliate links, etc.) but yes, if you fail to comply by their rules, you’re at risk of being shut down (and losing all the commission you’ve racked up). SO, don’t be a dummy, read the terms and conditions thoroughly and make sure you’re not breaching them.
There are two ways to approach affiliate marketing: You can offer an affiliate program to others or you can sign up to be another business's affiliate. As the business driving an affiliate program, you'll pay your affiliates a commission fee for every lead or sale they drive to your website. Your main goal should be to find affiliates who'll reach untapped markets. For example, a company with an e-zine may make a good affiliate because its subscribers are hungry for resources. So introducing your offer through a "trusted" company can grab the attention of prospects you might not have otherwise reached.
