Welcome to the Q&A Forum

Hello there, Remember that PA1 means that the page was not crawled by moz or it doesnt have anything of linkbuilding seen by moz. The question about passing linkjuice, is tricky. Every link passes linkjuice (some more, some less). You should focus in whether the link is ok to be there. The first check you must do is analyze for some spam flags in that page, or if it is a relevant&related topic with your site. That "PA ca go up by promoting the page" is not right. Moz's gives a number in their metrics in a 90% based on the backlink profile of that page/domain. (speking about PA, DA). Here some resources: What is Page Authority(PA)? - Begginers guide to linkbuilding - Moz - Targeted Link Building in 2016 - Whiteboard Friday Best luck! GR.
