I have a website that currently uses a .com domain for all traffic. I am targeting the United Kingdom, United States, Canada, Australia and New Zealand.
Instead of this, I want something similar to what eBay does; ie if I'm in Australia I automatically get directed to eBay.com.au
Aside from registering the domains and pointing them all to the same website, is there anything else I need to do?
Also, what are the implications from an SEO perspective of having exactly the same website but with different URL's for each region?
Would having a .co.uk URL rank me better in the UK instead of having a .com?
