I have some questions (maybe noob ones) and i hope someone can enlighten me. Does Page Rank have anything to do with Page Authority/Domain Authority ? When i am building backlinks whats is better to aim for ? For example lets say i have two pages: Page A has PR5 and PA30/DA70, and Page B has PR1 and PA48/DA81, what page will be better for me to have a backlink on. Until not so long i thought that PA is somehow related to PR, so if a page had PR2 it also had PA 20-30, but these day i noticed it isn't like that. I hope someone has an accurate answer. thx.
