Clickbank University (CBU) has some pretty good affiliate training, but not my #1 choice. I've been doing this stuff for almost a decade now. If you want to be an affiliate and build affiliate websites, then you are better off learning about that stuff from this affiliate training center. They've been around for 15 years, and have produced thousands of success stories (some of which I've personally mentored, since 2012).
Free traffic, such as organic search engine visitors, video marketing, or social media/forum traffic, can be a great way to get highly relevant visitors to your website without paying for each visitor. Building a platform that delivers free traffic can be a great long-term affiliate marketing strategy. However, the downsides of free traffic are that it can take a lot of time and effort before you start seeing results, and can be unreliable.
Start by taking other courses you’re interested in: Not only is this important competitor and opportunity analysis, but it also gives you an idea of how a course could or should look and feel. What’s the pacing like? Is it via email, video, in-person chats? Once you understand how you want your course to look, it’s time to decide what it should include. Those same courses are a great starting place. How can you make your course better or more interesting? Do you have experience others don’t?
