Overview

You need a footprint on Internet, something like a base which will remain active 24 hours a day - 7 days a week.

You may either own a piece of Internet (domain name) or share your presence with someone

Either way - you are making sure that customers can still find about you when you and your sales stuff have gone to sleep.

Remember - what's night for you may be working hours for your customers at other corners of the globe.

Owning your site or sharing - both has its advantages and shortcomings
