The website is already understood as required for any serious business. Still many feel they can do without one. They will eventually have to change their minds. The website is the new business card. But not just, it is better in every way.
The Website is your business's 24/7 business card and so much more. It is your "always on" marketing message that you can direct people to as a part of all of your other advertising.
Many local business still see the website as something for global businesses who need to target the audience that the internet is capable of reaching. But things are changing. People are changing.
People are using the internet as an information gateway to their world, local and global.
Even if your business is right down the street, today's potential customer is still going to "google" for you, for your hours, for your prices... and possibly late in the evening. So even local businesses need a website to represent them and make them available to today's shoppers.
For these businesses, there are plenty of great domain names left. If the business is local to "Amherst" then "theirbusinessnameamherst.com" is perfectly suitable and will actually give them an edge in search engines. This is because people are savvy about "googling" for local business. They google the service and their city and up pops your business.
While it may be tough to get a great domain name for going global, there is still plenty of room for small business to gain the edge in their local areas.
