Many advertisers are unaware of the potential of the affiliate marketing business model for their own businesses, in fact, most small businesses have never heard of it. But imagine marketing your products only to interested people for no upfront fee. Paying only when you get results is a risk-free way of advertising that requires no marketing budget to get started. As you can imagine, this is great for any start-up business with little funding for marketing their new brand.
If you have graphic design skills then you could make money online by creating and selling your own design elements, like templates, fonts, graphics, and other assets. This is a great way to earn extra money, and build up a portfolio of work, which could lead to you picking up freelance graphic design jobs. Websites like Envato Elements pay you a fee per element sold, which can become quite profitable if your work is popular.
