Hi, I am new here however I am pretty familiar with backlinking and lots of seo practices. I have a few concern about how to build backlink successfully for new sites. Everytime I build new sites, I tend to never do blog commenting, but I do a lot of directory submissions and social bookmarking. I know that I can rank sites, but do you have to prepare new sites with lots of blog comments and some social bookmarking, before taking out the secret weapons like using spun content on web2.0 and manual/mass article submissions of 50+? If anybody can accurately explain to me how effectively blog comment, and do article submission using white hat methods or software please let me know!
