Don't over think it of course but here are some guidelines: - Not longer than 7-8 characters - If you go for something unconventional, it should be easy to pronounce (very important. "Google" was unconventional but easy to pronounce) - Try not to use a dash or even numbers unless it is relevant like 411.com etc. Because if you do, then I have to think. Is it 1 or one ? - Don't make me think if I have to type your domain on my browser/phone etc. Spelling should be easy too - If the name gives me an idea of what you do, really great. But not required. For example, careerbuilder.com gives me an idea but monster doesn't. If I never heard of either, i can easily guess which one is related to careers and jobs potentially.
