After reading hundreds of great threads in BHW, there appear to be two conflicting theories on how to achieve success. Would love to hear from experts and anyone who has first-hand success or failure on this: The first theory is that Quality of backlinks matters. So an article in Ezinearticles (PR 6), a page on blogger (PR 8), or a bookmark on diigo (PR 7) should be the most worthwhile. The second theory is that Quantity of backlink matters. So a tool like Xrumer or ScrapeBox would be most effective, even if they are using low-PR sites. Some BHW threads talk about thousands or tens of thousands of backlinks. Some questions: 1.If I have a Blogger page that links to my main site, what is the benefit of building links into it using social bookmarks, comments, profiles? It seems that my Blogger page or Ezine Article, with a PR of 6-7-8, is not going to benefit from further inbound links? OR? does my single Blogger page not really have a PR of 8? 2.If Blogger is a NoFollow site, is it of any use in generating inbound links to my main site? Should the focus be only on Follow sites such as blogrolling, which is a much smaller universe? (Article sites are often **************** too.) What tools are best for posting content in multiple blogs that you own? 3.If Quality is supremely important, than what good does it do to have low-PR sites generated in the Quantity theory linking in to my site? How can the claims of success of 1,000s of mass comments be true if Quantity does not matter? 4.If Quality matters, then what is the role in a linkwheel of the new hubs/blogs, which by definition start with low PR? 5.What do you see as the advantages and disadvantages of these methods of building large numbers of backlinks, and what tools do you recommend for them? a.Social bookmarking b.Blog comments c.Forum posts d.Profile creation (with or without the above items) 6.A related question is about LinkWheels. Some people would ascribe them magical powers, but it seems that they are nothing more than a focused set of backlinks. If a bunch of PR1 sites are linkwheeled together, they really can?t generate that much juice. And if they can generate more juice, then it is only logical that using hundreds or thousands of low-PR links from outside-the-linkwheel comments and forums would be much much more powerful (Quantity over Quality.) 7.Putting conjecture aside, what are the actual experiences, or experts outside of BHW saying about penalties for any of these techniques? For the purposes of discussion, assume that the main money site has multiple pages, lots of original content and products, and is not a rehash of PLR content or ClickBank products (nothing wrong with these but want to keep the discussion focused on offsite techniques.) Also assume that Yukinari84?s recommendation of ?quality over quantity? content is followed, and: -articles and posts are original, and spun to at least 40% uniqueness -comments, social bookmarks, etc are spun -proxies are used Thank you in advance for your insight and opinions!
