Hi All Targeting same content for different Geo's what are the problems will be taken place. for example the content in xyz.com is same as usa.xyz.com. and in.xyz.com please advise..
You should assign the country according to the urls, like us.xyz.com should not be opened in india and visa-versa. You can do it through webmaster. So that google will not get any duplicacy problem and your main url xyz.com will get more traffic from there subdomain sites.
Yes, we are going to redirect the sub domain based on the Geo, and the sub domain will not open in any other regions. If it is ok, Then Google will won't consider the content as duplicate right.
