Physical products often have lower commission rates but higher trust because people can touch and return them. Digital products like courses or software usually pay more per sale but may be harder to convince people to buy. Returns and refunds work differently for each type too. Some affiliates prefer digital because there is no shipping or inventory involved. Others find physical products easier to promote since people already buy them everywhere. Both have advantages depending on the niche and audience. Which type tends to be more beginner friendly for someone just starting out?
