I keep getting different answers on how to effectively do social bookmarking. I understand they are mainly for getting links indexed quickly, but do they also provide linkjuice? I'm building a web 2.0 link pyramid as well as thinking about placing the following types of links in the 1st tier of the pyramid. Social Network High PR Blog Comments Manual Forum Links Docshare Video Which of these should I be bookmarking? Let's say that I have a total of 40 links that I want bookmarked, and I want to hire a service to do this. Lets say I find one that will do 120 bookmarks. Would I then be asking them to spin the 40 links so that there would be an average of 3 bookmarks per link? I'm very confused as you can tell, so how do you do it? Also, what questions should I ask the bookmark service to make sure they are doing it in the most effective way possible?
