  2. Domain name - find a simple domain name that can be printed in your future visitors memory. This is a great oportunity, to mark people brain with your domain.
    Be sure that your domain name is also relevant and for your site content; with other words, even if you get in users memory, if your content is not relevant to this you lost the game called Internet.
