Amazon customers are loyal. Beyond that, Amazon customers--especially Amazon Prime members--are more than happy to convert. According to a 2015 report, Prime members are said to convert at a rate 22 times greater than customers that shop with other top online retailers. So, if you can tap into that audience and appeal to their willingness to spend money with Amazon, you should see a good return on your decision to join the program.
Referral fees aren’t just for the products you recommend. Perhaps the coolest thing about the Amazon Associates program is that you receive credit for any sale associated with your affiliate link for 24 hours. So, if a customer visits the page of the product you recommended, but then goes on to purchase five more eligible items during that same visit, you will receive a portion of that entire sale.
