Merchants receiving a large percentage of their revenue from the affiliate channel can become reliant on their affiliate partners. This can lead to affiliate marketers leveraging their new-found status to receive higher commissions and better deals with their advertisers. Whether it’s CPA, CPL, or CPC commission structures, brands are willing to pay, and affiliate marketers are in the driver’s seat.
The final section of the course summarizes everything, explores the issues that might occur and ways to deal with them. Since affiliate marketing is essentially a part of online marketing, it will be helpful to learn how affiliate marketing integrates with search engine marketing, social media marketing, email marketing, etc. These strategies are analyzed from both perspectives, those of merchants and affiliates. Furthermore, the topic of online marketing and its segments is worth exploring more in the future as it can improve your success with affiliate marketing, regardless if you are a merchant or an affiliate.
Kevin Edwards, Global Client Strategy Director of AWIN, put it this way: “Data will continue to underpin the channel’s success. When one of the world’s most important marketers bemoans the state of digital marketing as opaque and lacking transparency, it sends a clear signal about the opportunity for affiliate marketing. P&G’s chief marketing officer made that statement earlier in 2017 and it should be a lightbulb moment for us about positioning the channel as the foremost, results-driven opportunity available to digital marketers. This can only be achieved if we get better at sharing significantly more data to facilitate a more three-dimensional and qualitative view of affiliate marketing beyond last click. Lifetime value holds the key to building a more rounded view of the power of affiliates to deliver quality customers.”

Now as to your comment on traffic it is true, traffic is important. But the truth is, acquiring traffic is easier than converting it. Plus we have many posts dedicated to traffic generation on this blog. Simply check this post, this post or this post. But must importantly, the reason why people struggle with traffic is that they try to promote a sales page or a heavily biased piece of content. Nobody wants to share that, nobody wants to link to that, and as a result you don't get traffic and blame your lack of success on traffic (like you did in your comment above).
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
