First impressions are hard to change. Your website might be great as-is, but Bandzoogle has put out a free eBook with 12 tips to improve your band's site. It starts with what seems pretty obvious (get rid of auto-play music), but includes tips for some seemingly minor details that overall can help make a great website. The eBook is a quick read, and free is hard to argue with.
