I have a website (.com) and my target audience is primarily at the moment Ireland and UK.
The site is hosted in ireland so placement in Google for country specific is good.
I am planning to set the sub-domain uk.websitename.com to load the same website (just a different alias to the same virtual directory).
Is this okay to do within Google? Any advice / pitfalls before I do so? I don't want to end up penalised by google.
