link searched as xxx.abc.com will show your links in more pages in content and everything but all dont count as backlinks by google.
The correct backlinks can be seen in the type - link:
http://xxx.abc.com
eg. my link
http://w ww.nobledirectory.com/blog/blue-horizon-template-for-phpld-20-and-306.html is shown in feeds page
http://ww w.linksarena.com/blog/comments/feed/ and is shown in google when searched for
www.nobledirectory.com directly.
But when searched for link:
http://www.nobledirectory.com then we wont find that feed page.
