Affiliate Network is the process where publishers/affiliates can generate income by promoting products or services of companies which offer affiliate programs like eBay, Amazon, JVzoo, Jimdo and so on. In other words, the Affiliate Network is a business that acts an intermediary between publishers/affiliates and affiliate programs (programs which offer people the opportunity to earn commission by selling their products and services). Affiliate Network helps affiliates/publishers find and participate more easily in affiliate programs which are suitable according to their website niche so that they can generate good income just by promoting products or services of other companies for which they don't need to have their own products or services and don't need to bother with shipment or delivery of products. Everything will be done by affiliate programs. The publishers/affiliates just need to promote those products and provide the unique affiliate link of those programs within their website to promote them so that when someone click those links from those publisher's website and buy the products in that affiliate programs, publishers/affiliates can earn commission completely in passive way. Affiliate Network is the best legit and passive way to generate good income online on regular basis.
Affiliates decide within their affiliate programs which banners or ads they're going to place on their websites. This decision is based on their individual calculations of which company ads their website visitors are most likely to be interested in. They will also agree to affiliate programs based on which merchants have the best commission structure, although the structure is not usually considered very high-paying or profitable.
