When picking your domain name keep in mind that using important key words WITHIN the domain name will help your site rank higher in search engines. So if you make and sell custom jewelry, it would serve you well to have both 'custom' and 'jewelry' in your domain name. At a minimum, you should have 'jewelry' in the domain name. For example if someone typed in 'custom jewelry' in a search engine, a site named DeesCustomJewelry.com would rank higher in the returned results than DeesJewelry.com and would bury a site named dees.com 100 pages back in the search results.

The best place I've seen to help you in your search for an available and relevant domain name is http://www.nameboy.com/ It's like a domain name super store. There is a name spinner where you put in key words and the spinner returns available domain names based on your criteria.

The owner of Nameboy.com also negotiates the sale of domain names. So if you are willing to pay for a domain name that you really like, contact the owner to see if he can help.

Some domain names are taken, but they are just sitting idle waiting for someone to pay a little more for a domain name that's relevant to their business.
