Hi Harry,
This is hard to speculate on without knowing the domain/keyword(s) you're mentioning - is there any chance you can supply that?
Typically, I would recommend using the Moz Bar tool to spoof your location to see if this is having an impact on the search results, but without knowing if the keyword you're looking to rank for is region-specific, this is hard to recommend?
In short, any more details you could provide would be awesome!
Regards,
Sean
