Choosing your website name
Recently we have been getting good results in page ranking choosing significant website names. For example if you are interested in ranking well for duck migration observation in canada, is a good idea to name your website canadaduckobservation.com or canada-duck-observation.com
Easily rememered names
But it is always important to have a website name that can be easily remembered. So maybe you need a shorter name. This is important for the word-of-mouth publicity, you would like that your site name is short and can be rememered.
For example even their offer books, music, suplies, ... amazon.com is a good name, and maybe onlinebooksell.com is not as good.
Remember that many promotion of your website can be out of Internet.
Finally, if you will concentrate in positioning your site you may choose the first option, if you think you will have very much word-of-mouth publicity it is better a easily rememered name. If you can combine the 2 , even better !
