Affiliate marketing may not be as plug and play fast to profit from as it once was, but its effectiveness is still in essence "business in an url" simple and convenient, so will always be "worth it" to set-up and go. In theory, just pick a niche that is popular enough that you have interest in, point your site or email content to the commission link, promote your funnel, and you're in the money. The company or service handles inventory, production, distribution and other business issues. What beginners need is exactly this kind of streamlined structure in order to get started, in any year.
