A domain name adds mobility to your web presence
On a basic level, domain names are important because the Internet's addressing scheme is not very effective without them. A short, memorable domain name can make the difference between creating a successful Web presence and getting lost in cyberspace. A domain name adds credibility to your business. A meaningful, memorable, relevant domain name is an invaluable asset in the brand process.
A domain name builds your brand
More than anything else, a domain name can increase awareness of your brand. If your domain name matches your company name, it reinforces your brand, making it easier for customers to remember and return. It will also be easier to win business via word of mouth because customers will remember your name and pass it along to friends.
The bottom line is that a well-chosen domain name can help a long way toward generating traffic to your website and building your reputation. That, in turn, will result in more customers and better sales.
A domain name adds credibility to your business
Having your own domain name makes your company look professional.
As there are some less than reputable sites on the web, you want to do what you can to prove that your business is one that customers can trust. This is because your business deserves their money. If you're not willing to pay the money to register an appropriate domain name, why would consumers think you'd put any effort into creating valuable products or services?
The right domain name can attract walk-in business
If you decide to register a domain name that matches the concept of your business (instead of your exact business name), you might attract web surfers searching for that topic.
For instance, a design company that registered Pistachio.de might get visitors looking for pistachio on the internet. Also, although search engine results are difficult to predict, Pistachio.de could show up more frequently in search results when someone searches for information about pistachios.
