Welcome to the Q&A Forum

Hey Guys, Weather it be OSE, ahrefs, etc. How do you determine if the link is worth using to build a backlink on? I know to look for a higher DA/PA and overall established links. I want very quality sites for external links (as we all do) but I also want to know what to look for and what to bypass when determining if I should build a backlink on the domain. These are a Few examples / questions i have sorry if they are basic: (the below are all specific examples) 1. If a site has an article and that article page is a DA 65 / PA 1 with Zero (0) established links to that article my backlink is on; would it be link building worthy? Should I leave a backlink, why? ex. lots of different blogspot.com blogs pointing back at my site..^^ Same domian, different blog any benefit? 2. If a site is a PR2 DA 30/ PA 32 with 14 root domains, 250 total links.... Would a link like this give me any benefit or should I skip links like this? Why? 3. What main factors do you focus on/look for and know when & when not leave a backlink to your site when using a tool like OSE, Ahrefs? 4. Should I even worry about a sites PR when linkbuilding since PR doesnt play that big of a role anymore opposed to high quality backlinks?  Ive seen PR 7 sites outranked by PR1 site with 200 high quality backlinks to it Thanks for any help and any help is GREATLY appreciated. 🙂
