Hello, I'm new to SEO and I'm looking to buy some specific expired domains for my niche to rank on Google. From what I'm reading backlinks don't matter all that much except when it's high PR ranking like PR6 and higher. 1 of those makes up for millions of smaller ones from what I'm gathering. So when searching for expired domains, what's the best way to figure out which domains have high PR backlinks already? And if they have a bunch of backlinks how do I figure out the PR to those... how does one acquire a high PR backlink? Is it highly advised to start with an expired domain from say 2010 rather than a fresh domain when ranking in google? Thanks!!!!
