Hi all, we have a .co.uk domain ranking really well in the UK and we'd like to start targeting the US market, hence we're considering a .com migration. Has anyone done such a migration without losing their UK rankings and did you go ahead with a subfolder strategy?
You could use hreflang to show the two domains are equivalent. I've seen people run dual sites for different English-speaking regions. I'm not aware of any major issues. It comes down to implementation.
