Thanks guys, As i asked if anyone knows any blog where I can comment in my niche?

 

I use this one method on blackhatguide that teaches you how to get unlimited backlinks via this one network =P

 

can u explain in very very simple steps all these things that you have just said in a single line that will be so generous of you.

 

Here are a couple good resources for free backlinks:

http://www.onewaytextlink.com/ (I like this one, cause it lets you check off the link directories you have added your site to.)
http://www.strongestlinks.com/directories.php

 

Submit to article submisstion sites and social bookmarking sites. Make good use of social networking too.
Should help attract traffic and improve PR.
