While posting a comment you must have to use hyperlink for link building else you would not get any back link.
Nothing new under the sun, I won't repeat what others have mentioned before me. The point is: Don't run after the latest and greatest link building "secrets or software" because you'd be only wasting your time
Thanks everybody for your kind suggestions. I have started building links for my website and I can see them indexed now. My website is indexed in Google and now getting good rankings. My rankings are improving gradually which is good for me. I am building links by Blog commenting and forum posting, will start article submission soon. Cheers. Kawish
