URL SEO
Ideally your url should contain the keywords that you are trying to target. For example if I was trying to sell blue widgets in califonia, the best url that I could buy would be bluewidgetscalifonia.com. You can separate the words in your url using a hypen which google will consider to be a space i.e. blue-widgets-califonia.com but it has become an internet convention that people generally don’t use hypens. It is best to always opt for .com over country specific domains as people will presume that all internet addresses end in dot com in the US and UK. When creating other domains for other countries its generally best to use the domain of that country. For example .es in spain and .de in germany. Again for SEO it is best to host the domain in the country that you are trying to sell your product in, as search engines will place presidence on rankings in that country if your domain is hosted there. This goes for domain names as well as space, although you can redirect your name to the name server of your website, its advisable to host your website in your country, more specifically your locale.
