Amazon will have you work on micro-projects that require some sort of human interaction. Tasks can include translating a paragraph into English (or another language), rating the search results for certain keywords, or reworking an article. The tasks are simple, and you will be paid a small amount to complete each. But if you do enough tasks quickly, you can make a respectable amount of money.
Ask for VIP (sometimes called “tiered”) commissions. Many affiliate programs have different commission levels. Usually the standard commission level is made public, but higher commissions are offered to higher performing affiliates. Sometimes you may be bumped up to “VIP affiliate” status by the advertiser, but most times you have to ask if there’s a higher tier and how you can get there.
