Google Query

This is the query that is sent to Google when domain's Link Popularity checked (the string that you have to enter into text box on www.google.com). Users use "domain.com", "www.domain.com", or even "http://www.domain.com". By default, the program uses link:domain.com request and it's the best choice if you need to estimate Google Page Rank.

You should use %s to replace domain.com. Thus the default request string is link:www.%s.
