Hi All , I have three Product sites that only sell products to USA citizens. In My Google sitemaps "settings" should I use the "target USA" option and save the change? Are there any hidden downsides to doing this? I have a lot of decent listings which I wouldn't want affected. My 1st thought was, that it would be good for my listings, even possibly get a boost? Would anyone please give their take on this feature and recommendations? Thanks!
