I am trying to understand the use of Top Level Domains. Do they help from a SEO perspective? Lets say I have a US site and a Canada site. For US, I create www.foo.com and for Canada I create www.foo.ca. Does this provide better functionality, or is it better practice, than www.foo.com/us/ and www.foo.com/ca/?
Thanks for any insight given...
foo.comis the second level domain; “com” is the top level domain. – Gumbo Mar 1 '11 at 17:14
