If you do not update your site on a regular basis you could not only lose repeat customers, but you could also hurt your sites rankings in search engines. Remember that people who come to your site are very likely interested in buying your products. Make sure you keep them informed of any and all new product lines. Some site owners even post news about their business and family on a regularly updated blog. It's also not a bad idea to update your show circuit on your site as well. If you let people know when and where you will be on a certain date, you can actually increase your real-world sales through your online entity.
