Ever since the idea of online auctions came into existence, the online selling market has been on the rise. Many are interested, but don’t know how to get started. There are still all kinds of ways to make money by selling online, whether you’re selling what you already have or buying and selling like a store. Before we get started, here are a few general tips when selling anything online:
Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs.

Now, it’s time to start creating and uploading content. Make sure you’re using a high-enough quality camera (most smartphones will work but I’d suggest at least having a tripod so your footage isn’t shaky), but don’t worry about being perfect at first. The beauty of YouTube is that you can continue to test out different content and styles as you find what works for you. Instead, stick to a regular schedule to build up your subscriber base.
If you own a domain name or a website (even a defunct one!) or a mobile app… and you want to sell it off, you should visit Flippa or Sedo or GoDaddy Auctions. On these websites, you can set a base price for what you’re selling and then perspective buyers bid in an auction format. Such a model maximizes your earning from selling domain name or website or mobile app.
