No, they are two completely different things. Reseller Hosting allows entrepreneurs to purchase and sell hosting products that already exist. Resellers also have the option of completely rebranding a product, even creating their own prices.
In contrast, affiliates do not buy products nor do they own products. Affiliates have one job, and that’s to successfully direct new customers to the host website they sign up with. The only time an affiliate earns a commission is when a new visitor makes a purchase. Each company in charge of creating their commission rates. Companies also supply affiliates with affiliate links, special codes, banners, etc. This allows them to track the traffic and sales an affiliate generates.
