There are things like solo ads that you can buy or join up with JV partners to help sell whatever it is that you're peddling. But at the outset, you're going to find it difficult to succeed in the internet marketing field. Ensure that you learn the right skills along the way so that you can become an effective online marketer. It doesn't matter how slow you go, as long as you don't stop, you'll reach your goals.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.
