|Selecting A Name
When selecting a domain name there are a few things you should consider. In order to achieve the following objectives you might want to consider registering a couple domains.
1) Brand name Recognition (ie. YOURCOMPANYNAME.COM)
2) Search Relevancy
example: All other Search Engine ranking criteria aside. A search for "Car Sales" would give "Car-Sales.com" a better listing than "MeowMotors.com".
Another VERY IMPORTANT aspect of relevancy (which is often overlooked) is LOCATION. If you only sell cars in Connecticut. ConnecticutCars.com would help (literally) eliminate a world of competition in search engine rankings.
3) Direct Results (Self Advertising Domains)
4) Find a Name that is Short and Easy to Remember
If you need help finding a suitable name there are sites where you enter keywords and click search. The site will give you a list of suggested and available Domain Names.
Namedroppers - Domain Name Searching Service.
Another way to find which names are available is to search directly from Domain Registars.
