I was thinking of buying some PR4-PR6 domains and then 301 redirecting those domains to my Tier 2 Web 2.0s that are part of my forthcoming PBN. What I'd like to do is protect the web 2.0s so I was thinking I could blast the domains with backlinks through GSA, etc. My questions are: 1. Will the linkjuice from the redirected domains be transferred to my Web 2.0s? 2. If Google decides to classify one of the domains as spam, will the Web 2.0 be protected from the spam rating? 3. Any other tricks on how to architect this? Thanks in advance!
