Courses are often popular in affiliate marketing because they usually offer higher commission rates than tools. Digital courses do not have production or shipping costs, which makes it easier for companies to pay affiliates generously. A single course sale can sometimes bring in more income than multiple sales of a software tool. Another reason is that courses often target people who are eager to invest in learning and self-improvement, which makes them easier to sell with convincing content. Tools, on the other hand, may require more explanation and long-term trust before someone buys. But is this focus on courses always the best strategy? Could promoting useful tools bring more stable, long-term income compared to the quick wins of selling courses?
