New Sub-Domain for local SERP's in an International Site?

[ksmith29]

In my woodcraft site, I target all the users around the globe. But now I am introducing a new product for which I want to target certain parts of US only. Now, creating a sub-domain for my new product and targeting it for local SERP's. Will it be a good idea?? Can it influence my international rankings also? Share your opinions.

If you are creating a new sub-domain to target then it should not effect your international rankings. This process is quite normal but make sure that you properly setup your WMT account.
