Today I checked the back-links of a domain that isn't registered. For that I simply typed the below string in google.

Code:
links:sitename.com
I was surprised to see more than 100k search results. Then I added www before the URL and was again surprised to see that still 75k results were shown by google.

The domain name had a Hyphen '-' in it.. But still google was showing so many results for the search. Now I want to know does such backlinks really count??

Please drop-in your valuable remarks!
