Building trust with your audience is paramount in affiliate marketing, and the quickest way to lose trust is to recommend products either you haven’t used before or that aren’t a good fit for your audience. Also make sure you never tell anyone to directly buy a product, you are simply recommending the product. The more helpful you are and the more you make quality recommendations, the more likely your web visitors will come back for your expertise.
ClickBank allows you to join for free, and the approval process is virtually automatic, so it’s a great choice for people entering the affiliated game for the first time. ClickBank has a ton of information, including FAQs, walk-throughs, and videos available, so the barrier to entry is quite low. There’s also a (paid) program called ClickBank University with courses and assistance from experienced marketers.
