Affiliate marketing presents a very low friction entry into selling products online. While you do need some type of audience to sell these products or services to, you could make a significant amount of money from home while doing it. Some products or services have very high earnings per click. That means, if you play your cards right, you could easily make a large profit on conversions by driving traffic to specific offers as long as you target the right interests.
@Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
