It’s also an incredibly low-risk marketing strategy with a high ROI. Most other promotional channels require some kind of payment upfront and there’s a chance that it may not work. In these cases, you’ve lost some precious marketing budget and not gained anything in return. However, with affiliate marketing, you’re only charged once a sale is confirmed. You can define the payment terms as 60 or 90 days to allow for refunds or processing issues. An affiliate agency will generally charge a nominal amount to cover overhead and then leverage their relationships to build your affiliate network.  This format protects both parties cash flow and ensures you’ve already received the money from the customer before you have to pay the affiliate. It’s a performance-based method that rewards top-performing affiliates who refer genuine customers.
Along with that, Amazon is a complete SELLING MACHINE! What I mean by that, is they have drilled their conversion rates down to the last detail. Typically I can convert traffic I send to Amazon from my affiliate sites around 12%. The reason why it works so well is that the moment people land on Amazon, they are automatically switched into "buyer mode". Meaning, they know the only thing left for them to do is BUY. What that means, is all you have to do is get people to Amazon's site, and they literally do the selling for you.
Let no one tell you that email marketing is dead. An email list is crucial for every affiliate marketer. You can start building up your email list with a lead magnet (like the information products mentioned previously) or even just by encouraging your audience to sign up for your updates. You can then push your content to this audience via email and also direct them to your affiliate offers. Don't be sleazy about the sales, but if you build up enough trust with your email audience; when the time comes, they will not mind purchasing a product from you. 
Insurance comparison sites are fulfilling a need. People don’t want to spend hours looking for insurance, and they don’t find it fun. If you’ve ever found anyone who enjoys this kind of activity, they could possibly be a little crazy. Both Compare The Market and Gocompare.com have not only made the tedious process of finding a policy infinitely faster, they’ve also made it fun. (Think of the free meerkats and the Gocompare man you love to hate.)
Many affiliate programs run with last-click attribution, where the affiliate receiving the last click before the sale gets 100% credit for the conversion. This is changing. With affiliate platforms providing new attribution models and reporting features, you are able to see a full-funnel, cross-channel view of how individual marketing tactics are working together. For example, you might see that a paid social campaign generated the first click, Affiliate X got click 2, and Affiliate Y got the last click. With this full picture, you can structure your affiliate commissions so that Affiliate X gets a percentage of the credit for the sale, even though they didn’t get the last click. 
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.
