I have 2 questions and i don't have time to test or money to spend so i hope someone can help me out with some answers. I'm going to buy some links, i have the option to buy a PR4 link on a very crappy website with low PA/DA and low majestic trust flow as well - or to buy a PR2 or PR3 link on a high DA/PA (around 30) page; both links would be contextual - which one is better for ranking, the PR4 or the lower PR but higher DA/PA ? I also have the option to buy 2 expired domains: one is PR4 with very few links (20-30 links) and a low DA/PA (around 10) and the other is a PR2 with more links (around 100) and higher DA/PA (around 20-25). Which one is better? I'm asking this because lots of people say check the DA/PA as well, but as far as i know google only uses their page rank - and the other signals (DA/PA, Majestic Trust Flow or Ahrefs rank - are not consistent). So which one is a better indicator? PR or DA/PA? Or maybe even Trust Flow or Ahrefs Rank?
