Every so often I get a new client that does not have any kind of company identity much less website and domain name. If they are in or entering a very competitive marketspace finding the right domain name can be challenging when we are concerned with the search optimization benefits of the domain name. For example if you are starting a new flooring business in Los Angeles, you may find it very difficult to find a variation of Los Angeles Flooring that has not already been taken. As domain names are so affordable (practically free) many people in an industry will buy a number of them just in case they decide to use them at another time thinking they may want to dabble in the domain name reseller business. If your domain name is taken try using a tool like your yourdomainpick.com to help identify similar, alternative domain names that will suit your purpose as well or better.
It is always disappointing when you find the name you want is taken and worse, taken and not being used for anything.
