I have a network of 10 High PR Blogs (PR3-5). I am looking to create my own private blog network so I can build links to my money sites. I looked at Article Marketing Robot, and it seems like it lets you create your own sort of SEO Link Vine system, where you can write an article and spin it and post it to all of your blogs. My question is, why not just put all my money sites in the blogroll of my 10 High PR blogs, and just let WP-Robot post to my blogs every day on autopilot. What advantage is there to the Article Marketing Robot method? It seems like I would lose Link Juice after the posts fall from page 1 of my blogs, and if all my money sites were just in the blog roll I can keep my juice. What do you guys think?
