In terms of making money, the sky is the limit. Most affiliate marketing programs usually range anywhere from 15% to 40% commission but I’ve seen ones as low as 1% and as high as 100%. Affiliate sales are usually paid either based on a percentage of the sale or a flat fee.
A review site, on the other hand, focuses more on reviews of products and services related to the industry. The advantage of these review sites is that people usually check out these websites when they intend to make a purchase, so the possibility of someone using your link to make a purchase is much higher. One more advantage of review websites is that you don’t have to post updates regularly, instead of waiting for product launches in your sector to be able to truly capture readers with reviews for a product they might want.
