I would like to know, if I buy expired domains with great backlinkprofile and then 301 redirect them to my moneysite will that help me boost the SERP? In this process is there then anything I need to have in mind? 1. Different hosts 2. Maybe the domain needs to be online and indexed before making the 301 redirect 3. Is it better to make the redirects to my tier 1 instead of the moneysite 4. Should I linkbuild to the redirected domain with related keywords Etc..
