Affiliate marketing has grown quickly since its inception. The e-commerce website, viewed as a marketing toy in the early days of the Internet, became an integrated part of the overall business plan and in some cases grew to a bigger business than the existing offline business. According to one report, the total sales amount generated through affiliate networks in 2006 was £2.16 billion in the United Kingdom alone. The estimates were £1.35 billion in sales in 2005. MarketingSherpa's research team estimated that, in 2006, affiliates worldwide earned US$6.5 billion in bounty and commissions from a variety of sources in retail, personal finance, gaming and gambling, travel, telecom, education, publishing, and forms of lead generation other than contextual advertising programs.
But you’d be surprised at the number of times I’ve visited a blog post or received an email that gives a glowing endorsement of a product or service, but doesn’t include enough links back to the company’s website. Sure, the brand’s name is mentioned throughout the content. Yet, that brand name is not hyperlinked with an affiliate link; instead, I need to scroll all the way to the bottom of the page or email in order to find a clickable link.
