In affiliate marketing, problem solving keywords and product keywords both have their own use, and it is important to understand the difference. Problem solving keywords are when people search for a solution, like how to fix slow laptop, and then a product can be recommended as the solution. Product keywords are when people already know the product and are close to buying. Many people say problem keywords bring more traffic, but product keywords bring more buyers. So it looks like both are important in different ways. Which one should be the main focus?
