rel=nofollow is not working
As I browse websites, I found this blog article dated Jun 16 about nofollow no longer works to affect or to sculpt Page Ranks. Whether you use nofollow or not, all the links are being processed equally from one year ago.
Commenting is a very good way of building backlinks. But just remember, spam won’t do it. It has to be real comment to be effective.
So everybody start commenting now.
