Graphic Design to Give Your Shop the Edge
Best of my tips: Concentrate on getting nice and clear photos, have some unique products (find a niche), create pretty but simple and consistent packaging, have a memorable name and logo, use Metatag Analyser on each website page to check your meta tags and descriptions are search-engine friendly, use Project Wonderful if you want to advertise on other sites, approach suitable blogs to try and get your shop featured, have regularly updated information and perhaps tutorials on your website to try and drive traffic to it, and lastly (if you have good photos) submit your products on Craft Gawker.
