Duplicate Content On A Subdomain

[jasarrow]

Hi,

We have a client who is currently close to completing a site specifically aimed at the UK market (they're doing this in-house so we've had no say in how it will work).

The site will almost be a duplicate (in terms of content, targeted keywords etc.) of a section of the main site (that sits on the root domain) - the main site is targeted toward the US. The only difference will be certain spellings and currency type.

If this new UK site were to sit on a sub domain of the main site, which is a .com, will this cause duplicate content issues? I know that there wouldn't be an issue if the new site were to be on a separate .co.uk domain (according to Matt Cutts), but it looks like the client wants it to be on a sub domain.

Any help/advice would be greatly appreciated.

subdomain or different domain it's still an identical site. it would be better to have it on a co.uk domain, i would convince the client to do that - why do they want it on a subdomain?

Anyway, subdomain, main domain in a directory, or different domain. Google will be fine with it as long as one site is geo targeted for the US and the other site is geo targeted for the UK. Duplicate content is filtered not penalized, so it is getting properly filtered this way. One site showing in the US and one showing in the UK.
