How can I find affiliates? Affiliate marketing is a rapidly growing advertising and sales tool in the internet sphere. In fact, a 2016 BI Intelligence study found that affiliate programs are one of the major drivers of e-commerce sales. They account for 15% of the digital media industry's revenue each year — a percentage that's equal to sales resulting from email marketing campaigns. As a blogger with an established audience and one or more items for sale, you're uniquely positioned to use affiliate marketing to promote and sell your products.
