Coming Soon...
Let's say you've registered your domain name, set up your email, and you're working on an exciting, creative design to really impress your customers. Are you doing anything wrong?
You might be, if people who find your domain can't get information about your new business. Don't wait until you've built an amazing site to create something (anything!) at your domain to tell surfers that your doors are open. Anyone who reaches it before you've launched your site may never come back. So you might have already lost your first (or second, or third...) customer while you were finalizing your design.
Some registrars automatically provide Web pages with every domain name registration so you can at least create an online business card that shows your email address and phone number.
