Link juice is a way to get visitors from other websites. For example, if you are submitting your website to social networking sites as digg, reddit, Facebook, twitter, linked in etc... And when you get visitors from there it is link juice to your website. Link juice is also helpful for getting good ranking for your website on search engine.
You are wrong my Friend.
Link Juice comes from Backlinks and nit from Visitors.
If your submitting your site to High Pr site like 9 then Your site will also get the link juice (PR) from that site where you submitted your site.
