Are links from 5-10 pr2 domain of any random niche any relevant for some site? Found a person selling 5 blogroll links from pr2 expired domains, so are they worth it? He is offering them cheap. Links are permanent and do-follow, so will they help my site with SERPS? Also these domains have PA /DA both around 15-20, a couple of years old and only 10 - 12 backlinks pointing to them. Thanks for your advice in advance!
