The key is to make the class sound unique and irresistible. Don’t just teach a cooking class; come up with specialty cooking classes. You might teach a class on how to make artesian breads, or cinnamon rolls that rival Cinnabon. The possibilities are endless, and if you consistently offer educational and fun classes, you’ll have people signing up over and over again.
Research individual companies in your desired niche: If possible, it’s always better to become an affiliate directly with a company (if they have an internal affiliate program), as no one else will be dipping into your commission rate. This is the preferred route for most of the prominent affiliate marketers, including Pat Flynn. Unfortunately, it’s also the most work, as you’ll have to do the research yourself to see who offers programs (they’re usually listed in the website footer).
