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.
Advertise! Whether you pay for advertising or you trade advertising with related websites and blogs, or you use free search sites, the important thing to remember is to put in the time and keep track of what works. Search out other websites and blogs with similar content and leave comments with your contact info. There are services that will do all the marketing for you for a fee, but to start out, you can do the marketing yourself. Fiverr.com will advertise your website starting at $5.
