Hi I wanted to clear some thing for those who buy expired domains for building their PBN. 80 % of us don't find expired domains about our niche, so we buy some PR domaina, with good DA and clean link profile then we upload our content which is totally different from the original niche of this domain. What happens when we do that ? if Google treated it as a new domain that's will be good, but the problem they would treat it as a domain with a spam backlinks as the new content don't fit the old link profile. If you have a got a website about web design and you are building Backlinks in sports website, what will be the result. My solution for that, buy new domains, build backlinks for it, some manually (Tier 1) then you can use automatic tools. Looking for your opinions.
