You might be curious about how the merchant knows which affiliate is responsible for the purchase. That’s actually the easy part since every affiliate is given a unique link that tracks each product they promote. This lets the merchant track all referrals using cookies to ensure that they know exactly how much money they’ve earned thanks to each affiliate (and what to pay them in return).
Let us just say you have written an awesome article, but the affiliate products you usually sell will not fit with this content. You have a feeling that people who read this content might want to buy a particular product. For example an article about keeping children safe online might be suited to software like Net Nanny rather than an Antivirus program. The need would be direct and far more precise.
The other type of Amazon affiliate link I use is when I’m mentioning a product in passing and/or a new product is announced. For example, when Nikon announced the Nikon D300s we immediately posted about the news because it was a notable and anticipated camera announcement. The camera was not yet available in stores and we were not able to get a review sample yet – but it was available for Pre-Order on Amazon so we linked to it.
When there are multiple affiliates involved in one transaction, payment gets much more complicated. Sometimes it’s even possible for affiliates to jump in at the last minute and claim commissions for customers brought in by other affiliates. Successful programs use multi-channel attribution to ensure the affiliates that create the most value get paid the most.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
