can someone explain to me how to use a PR5 or PR6 domain to gain more traffic to an existing domain? does one just make the PR6 domain redirect, or place links all over for the PR0 domain on the PR6 domain, or what? Thanks in advance
Stat working on PR 5, 6 domains for unique content and leave PR0 domain before high PR domains start loosing their PR.
Yes pagerank does bring traffic. I would recommend building up your site on the pagerank domain as the pagerank is partly from backlinks and it can start bringing in traffic from those backlinks.
Do some unique blog post and try to be active there if you want the whole link juice. then you can link back to pr0
