Now hold on a second I think if you're going to look at statistics you should ask a few more questions... Comparatively, how many brick and morter shops are having to close? I'd like to see if their rates match. Keep in mind, i'm sure there are far more online stores than brick and morter shops but you get my point. Why do any businesses close? Bad service, higher prices, technical difficulties..etc. I'm willing to bet that there's a difference in survival rate for those who mix online and offline business. For instance, people who don't know enough about marketing to make their business work won't think to advertise in other offline places. I think the goal of any business, but especially online business is to find the best ways to get your name out there. Tell people that you are there and they will come knocking on your door. Maybe not ALL of them, but the ones who need you.

Anyways... I'm done rambling
