If an affiliate changes the terms of its program, your revenues could be directly affected. Choosing the wrong affiliates can also be problematic if your blog or website audience doesn't feel compelled to buy their products or services. With the affiliate-marketing industry experiencing a boom, you’ll also have to contend with competition from other marketers shilling the same affiliate products.
The better you learn and understand SEO and the more strides you take to learn this seemingly confusing and complex discipline, the more likely you'll be to appear organically in search results. And let's face it, organic search is important to marketing online. Considering that most people don't have massive advertising budgets and don't know the first thing about lead magnets, squeeze pages and sales funnels, appearing visible is critical towards long-term success.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
