About two months ago I changed my site's geo location to target UK. I've been ranking consistently well in the google.co.uk domain. (over 25 different keywords, all in top 10 positions). For the same set of keywords, i'm doing just fairly well.. At the max 3rd page. My question is, if switching back to no geo location targeting would affect my SERP positions for the .co.uk domain? Also is it because i'm geo targeting UK, my rankings in the general google.com domain is ranking badly? Thanks.
