These are just the key features, but the platform offers many more. Check them out and use all the features on your way to becoming an affiliate marketing pro. However, some say the amount of knowledge might be overwhelming for new Wealthy Affiliate users, therefore take one affiliate marketing training course at a time and ensure you learn it and put those tricks into practice before you move on to the next chapter.
#2: Another great program is Jon Dykstra's Niche Tycoon. This focuses on paid traffic and outsourcing content to make money with Google Adsense (and similar programs). It requires a bit more of a budget, and also has less of a support community than Wealthy Affiliate, so it's best for people with a bit of online marketing experience and some money to get their business going.
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).
For a slightly different take on the subject and figuring out how to get targeted traffic onto your promoted links, you must have a look at Affiliate Marketing: Instant Traffic to Affiliate Links. A quick look at the reviews will help you decide if this is the exact course you are looking for. Sometimes the right approach is what is required to make a campaign work, this one might just work for you. You can see more details here.
Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.
