Search Engine Optimization Voodoo for Web Developers
SEO strategist Nicholas Carroll wrote the SEO entry for the 2010 Encyclopedia of Library and Information Sciences. She says the domain name you choose is half of the game--you should have the domain in hand, hopefully with keywords within that domain, before you even before you name your product or service.
Website owners and online businesses need to be adaptable with their product or service, especially if a given domain name is not available. If that's the case, it's time to consider renaming your offering. The name should be original, and you should avoid using a name that has other firm's calling card all over it.
