I want to rank my website globally. My website ranking for google.co.in is good but not in other versions of Google(Google uk, Google Canada, etc.) so can anyone help me?
Firstly you should try to find out the keywords related to your website from global competition. Then work on that keyword by posting content and by making backlinks on targeted country domain sites.
Set up your webmaster tool as international location. There is a useful option - international targeting - country.
if you want set your location globally then fix "unlisted" otherwise choose country name.
