If you want to run an online business, one of the easiest ways to do so is by running it on an online marketplace. In other words, instead of creating your own online store, you can try creating a store on platforms like Amazon, eBay, Etsy, etc. and sell your products through these platforms. Some online platforms are free to use, you pay only when you generate sales. Whereas some online marketplaces have listing fees. Your main expenses for running a business on an online marketplace are related to marketing and advertising. There is a lot of competition so in order to improve your product visibility, you will have to run ads. If you plan your ads well, you are likely to generate profits
