Hi, just started a new site a few weeks ago. What do you think about Social Bookmarking and Profile/Edu Submitter for High PR sites to build some quality backlinks to your naked url? Use them also to get some diversity because now I used only 10 expired tumblr, 2-3 blog comments, 2 forum links and 2 guest postings on low DA sites (10, 22). 1. Do you think it's safe to build like 50 social bookmarkings (xing, pinterest, diigo, delicious, and more) + 50 Profile backlinks (apple, amazon, flickr, ted, dell, and more) + some .EDU profile backlinks to your moneysite? 2. What do you think about image submission, audio submission and pdf submisson to moneysite?
