There is an increasing number of online craft marketplaces, such as Etsy, Amazon's Handmade, Artfire, and many other specialist sites. Selling online is a viable proposition for anyone with access to the internet. No technical skills are required to set up an online store within these online handmade marketplaces. Starting a store on Etsy is relatively quick and easy to do. But, you will need to work hard at taking top-notch photos of your cards, crafting superb product descriptions, and learning about search engine optimization and keywords to really get your online business off the ground. Don't worry if this sounds daunting, the Etsy seller's handbook is a fabulous source of information and will help you get started.
Identifying your target market is key. Your target market is the group of people who will buy your cards. Getting the word out about your product is your marketing plan. Knowing your target market will help you define your prices and determine where to market your cards. For example, if you sell cards which will appeal to hipsters, your target market is going to be very different than if you are selling cards for a kid's birthday.
Think about the product that you are selling. Put together a product development plan that shows how versatile your idea is. Can it grow? Does that product spawn other products or idea that can potentially sell? While simply making some cards and putting them up for sale might prove successful, you will likely need more than the initial product. A product development plan will help take out the guesswork of how to make products that sell.
