Pay per sale is probably the most lucrative option but it’s also the hardest. You will only get commissions once your customer buys the product or service. This is usually reserved for the more experienced affiliates as beginners will have trouble closing the deal. In this model, all of the risks are on the affiliate so merchants love this option the most.
One of the best ways to offer value to your list and promote your affiliate links in an organic way is through an email course. This is essentially a how-to guide in email form, sent out in multiple emails – and by the way, it’s also a great incentive to get people to sign up to your list if they get a guide in return.

The reason why it’s so profitable is due to smaller/lesser competition (since most sites are written in English) and using the native language makes it easier for them to build a rapport with the local audiences. Check out how to launch a multilingual WordPress site.
