Header says it all... I am still learning, could someone explain how these products exactly work? I have blogs and been told to look into this...
Do you mean link juicer? If so, it is a product that you load spun content into and it distributes it automatically to various web 2.0 properties, document sharing sites and bookmark sites. Blog Blueprint is a blogging system where you submit spun content and it distributes it to a bunch of blogs. The blogs are owned by the owners of blog blueprint and, according to them, have a decent PR. Both have a monthly fee. Does that help? Lee
'link juice' is an expression people use to describe the amount of backlinks. For example, they may say 'The site is ranking on page one of Google because it has immense link juice rather than unique content'. No idea about the other thing, but I would say that no one person or small IM corporation can possibly own enough IPs to fool the major search engines. Especially when anyone can sign up for it, and backtrack all the site in the network in one fell swoop.
If you "get link juice", you get traffic back to your site. However, link juice is a term directly connected to Google's page rank. So, it's actually about a traffic that shows how important you are, rather than about a traffic that's useful to your site. It may look like the same thing, but it is not.
