Online business can be really good passive income sources. While you can generate passive income even by selling physical products, selling physical products require a little bit of effort. However selling Digital products can generate you a lot of money. Unlike physical products that need to be manufactured for selling, you can sell the same digital product again and again. Therefore, an online business selling Digital products is one of the best ways to build passive income. However, before you can start a digital product business, you need skills to create digital products and SEO and digital marketing to generate sales.
