You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.
The best part about being a YouTube Partner is that it’s free to join (although there are a few requirements but more on that later) and once you become a Partner and enable ads, you don’t have to do a single thing. Google Adsense will take care of everything for you. All you need to do is create quality videos and promote them so you can get more views.
