The best method to auction off your digital art and earn a reliable and steady stream of income is to get associated with a digital marketplace. Directly.me is a very popular option in this regard. You simply have sign up with the website; this can be done either through direct login through your email address or by using social media websites like Facebook, LinkedIn and Twitter. Before you upload your digital art on directly.me, you can upload some previews on websites like Instagram, Flicker etc and create a URL. This URL can then be pasted in the sales pitch (billboard) you will create to convince your prospective buyers. The whole process is simple and a strong network of user and affiliates means that the chances of your product being sold time and time again are plenty. This option also allows you to directly interact with the customers, thus putting you in a position to sell multiple products to a single user.
Directly.me is not the only option to sell off your digital art. There are other reputable options which allow access to interested customer. Some of the popular options include EBay, Etsy, Amazon, Imagekind.com, Cafepress, Craigslist, Artfire.com, DailyOriginal.com, EmptyEasel.com etc.
Another good way of promoting and selling your digital art is to create a dedicated website with a mailing list. Many people do not spend on creating a mailing list for their websites, and in doing so they let go of a significant amount of money which they make otherwise. Consistent emails allow your followers or subscribers to stay in touch with the latest products you are offering, providing you an effective mode of communication which is much better than getting searched out through the social media websites and various search engines like Google and Bing.
