Tradedoubler was founded in 1999 by two young Swedish entrepreneurs. They have offices in the UK and multiple countries throughout Europe, including Sweden, Germany, France, Poland and Spain. Their focus has always been to provide smarter results for both clients and affiliates through technology. In 18 years, they’ve amassed an army of 180,000 active publishers, connecting them to over 2,000 merchants in Europe and the UK. Many of these merchants are household names.
The terms of an affiliate marketing program are set by the company wanting to advertise. Early on, companies were largely paying cost per click (traffic) or cost per mile (impressions) on banner advertisements. As the technology evolved, the focus turned to commissions on actual sales or qualified leads. The early affiliate marketing programs were vulnerable to fraud because clicks could be generated by software, as could impressions.
With the ability to rank organically in search engine queries, bloggers excel at increasing a seller’s conversions. The blogger samples the product or service and then writes a comprehensive review that promotes the brand in a compelling way, driving traffic back to the seller’s site. The blogger is awarded for his or her influence spreading the word about the value of the product, helping to improve the seller’s sales.
Every network offers affiliates a way to filter through the numerous offers presented. Take the time to go through the various categories or search for specific merchants that you think would do well on your site. There’s no set of rules for filtering through the options; you’ll ultimately need to rely upon your familiarity with your audience and your gut feelings about what types of offers will perform.
The Negative Option Rule applies to sellers of subscription plans who ship merchandise like books or compact discs to consumers who have agreed in advance to become subscribers. The Rule requires ads to clearly and conspicuously disclose material information about the terms of the plan. Further, once consumers agree to enroll, the company must notify them before shipping to allow them to decline the merchandise. Even if an automatic shipment or continuity program doesn't fall within the specifics of the Rule, companies should be careful to clearly disclose the terms and conditions of the plan before billing consumers or charging their credit cards.

Amazon Associates is an affiliate marketing program run by Amazon which allows you to sell its products on your own website in exchange for a cut of the profits. This enables you to boost your product range, test new types of products on your audience or even build a full business around this and perhaps other affiliate programs. For small businesses that currently sell products online, this could represent a great source of added revenue, if you sell additional products through Amazon, without worrying about getting the products yourself. Amazon conducts the sales and ships them directly to the client.
Advertisers love affiliate marketing because it involves minimal risk. If a sufficient margin is built in as compensation for the affiliate, it becomes impossible to lose money. That’s because affiliates are generally only paid when a sale is completed (i.e., a lead is converted). Advertisers (or “merchants”) pay nothing for leads that don’t convert.
Website conversion is also a big issue. Affiliates often determine how much effort they will devote to promoting your product based on the Earnings per Click (EPC) that the merchant generates for them. This calculation is based on their commission rate and the conversion rate of your website. If you have a website that converts really well (gets people to make the purchase), you may be able to offer lower commission.
Understand the basics of how affiliate marketing works. Many online retailers who sell products or services offer affiliate programs. If you decide to sign up for a company’s affiliate program, you get a tracking link to put on your blog. When visitors click on that link, the link stores a cookie in their browser that remains for a set period of time, such as 60 days. If the visitor purchases a product from that merchant site within the time period, you earn a sales commission.[26]

Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement but must also click on the advertisement to visit the advertiser's website.
