Hi there!
I've been checking rankings in UK and Ireland for the last months and I found something really interesting...
"Belfast + keyword" - UK = 2º position / Ireland = 1º position
"keyword + Belfast" - UK = 14º position / Ireland = 1º position
*(same keyword)
I don't understand how it is possible... Website is not geo-targeted so Google has no preference for any of these countries...
Any ideas about why does it happen?
