Artfire is filled with lots of unique gifts and treasures for people to admire and buy. Obviously your goal by listing on Artfire is to sell your wares. You want to entice the customer to look at your store and then decide to buy. You hope they will see your creations and be overwhelmed and want to buy.
You need to commit your self to your store to get those sales. The biggest commitment is time. Of course time to create but also time to get your store together, take good pictures, write compelling titles and descriptions. Take the time to list new items and keep it fresh. Make it a point keep up with new tools and changes on Artfire or any venue you sell on. Take the time to learn new tricks and make a fan page and a blog. Put in a little effort. It will pay off in the end.
These points can't be stressed enough, with out some activity on your side, there will be no activity from buyers. If find yourself constantly saying but I don't have the time for that and just sit back and wait, maybe you want to rethink your game plan. Like anything else worthwhile, selling online takes effort and commitment.
