International websites .com/country VS country.domain.com VS country specific domains

Milan Direct now has milandirect.com

What is the best SEO path for us to pursue as we expand internationally?

should our sites be like:

[noparse]www.milandirect.com/au[/noparse]
[noparse]www.milandirect.com/uk[/noparse]
[noparse]www.milandirect.com/us[/noparse]

or

au.milandirect.com/
uk.milandirect.com/
us.milandirect.com/

or

[noparse]www.milandirect.com.au[/noparse]
[noparse]www.milandirect.co.uk[/noparse]
[noparse]www.milandirect.com[/noparse]

doesn’t matter in the slightest. Really. The Local TLDs with have a little more weight for local searches. But the effect is minimal at best.

In an ideal world, you would set the website on just one of them but set all three formats to redirect/rewrite to the real one.

Ideal would be milandirect.com.au - if you have the budget.
