Hi Buddies, I used to work on multiple link building tasks such as: social bookmarking, doc sharing submission, web 2.0, .edu backlinks,etc and blog commenting. However, recently I see that blogs commenting is making less value as they look too spammy . It's hard for me to find out the ones of PR3+ with less than 100 OBLs. Also, general niches, not relevant ones to my niche. So should I continue with this white-hat technique? Or quit it off? If I quit it, what is the best one to replace? Much appreciated for your helps, BHW members!!!
